INTRODUCTION

The masses of isotopes and the binding energies of nucleons, which are among the most important characteristics of atomic nuclei, are determined by four principal methods: mass-spectrometric measurements; measurements of the energies of nuclear reactions; study of the decay schemes of radioactive isotopes; and microwave measurements. In recent times not only has the number of measurements increased, but their accuracy has also increased severalfold. Therefore the existing tables of masses have to a considerable extent become obsolete.

In compiling new mass tables it became clear that, owing to the abundance of experimental data, masses can be calculated by various methods. This makes it possible to compare different measurements and establish the degree of their reliability. At the same time, using mutually consistent values, one can carry out an adjustment of all results and obtain the most probable values of the masses. When the number of measurements is large, the most accurate method of adjustment is the method of least squares. The best work on comparing experimental data and calculating, by the method of least squares, the most probable mass values of light atoms up to and including calcium atoms is the work of Dzhelepov and Zyryanova^104. In this work the atomic masses were calculated using all experimental data, in contrast to other similar works in which either only nuclear-reaction energies^597,487 or only mass-spectrometric measurements^600,70,71,601 were used. A great merit of the work of Dzhelepov and Zyryanova is that it describes the methods of calculating masses and gives all the initial experimental data that served for their calculation. This makes the mass tables of light atoms by Dzhelepov and Zyryanova at present the most reliable and convenient. For heavy atoms from platinum to californium the author calculated the masses and binding energies of the nuclei of all isotopes from decay energies, nuclear reactions, and a small number of mass-spectrometric measurements^212.

Mass tables of isotopes from calcium to platinum have, in practice, not yet been published, apart from a small number of individual values^297,464,598, which, as a rule, are far from the best. At the same time, by the present time quite a large number of different measurements have already accumulated, permitting the masses of a large number of isotopes of intermediate mass to be calculated by various methods.

Initially our intention was limited to comparing all available data from measurements of the masses and energies of isotopes from calcium to gallium and from palladium to xenon and, using mutually consistent data, to calculating the masses and nuclear binding energies of all isotopes in these regions. Because of the insufficiency and inconsistency of the experimental data, it was then impossible to calculate the masses of isotopes of atoms from germanium to ruthenium. During the work of compiling and reconciling the tables, the results of new mass-spectrometric measurements^464,510 and of some measurements of nuclear-reaction energies were published, which removed a number of contradictions and made it possible to calculate the masses of the isotopes of germanium, selenium, krypton, and on through molybdenum inclusive. A large number of mass and binding-energy values made it possible to find binding energies and masses of isotopes of technetium and ruthenium by interpolation along curves. Thus, the comparison of experimental data made it possible, with great reliability, to establish

most probable values of the atomic masses and binding energies of isotopes of all stable and most radioactive isotopes from calcium ($Z=20$) to xenon ($Z=54$), inclusive. The atomic masses and nuclear binding energies of 383 stable and radioactive isotopes with atomic numbers from 20 to 54 inclusive are given in the main Table VI of the present work.

In calculating the masses and comparing the experimental data, the most probable values of the masses of light atoms established in the work of Dzhelepov and Zyryanova2 were used. All other initial experimental data are given in the present work in Tables I, II, III, IV, and V, with an assessment of their degree of reliability.

In addition, Table VII gives the masses of individual isotopes of medium and heavy atoms with atomic numbers 56 and higher, and the binding energies of their nuclei, calculated predominantly from mass-spectrometric measurements. The masses given in Table VII in most cases are obtained from only a single measurement and therefore are less reliable.

Below, all the tables, the methods of comparing the experimental data, and the calculation scheme are described, and also some separate conclusions and remarks are given.

I. INITIAL EXPERIMENTAL DATA

The initial experimental data necessary for obtaining the masses of medium atoms and the binding energies of their nuclei, compiled in the main Tables VI and VII, are given in Tables I–V.

Table I, containing data from mass-spectrometric measurements, is divided into four parts. In sections a) and b) the results of measurements of mass doublets are given. In section a) the mass differences of doublets $\Delta M$ are presented directly, and in section b) the differences of packing fractions $\Delta f$ are presented. As is known,

\[ \Delta f=\frac{\Delta M}{A}, \tag{1} \]

where $A$ is the mass number at which the doublet is measured.

The order in which the doublets are arranged corresponds to the increase of the atomic number (and for isotopes, the mass number) of that one of the atoms entering into the composition of the ion which has the largest atomic number. The degree of ionization of the ion is shown by a fraction placed before it, the denominator of which denotes the number of elementary charges of the ion. The mass differences are given in hundred-thousandths of an atomic mass unit. For the list of references see p. 168.

In the last column of Table I the “adjusted” values from Tables VI and VII are given.

In section c) of Table I the experimental values of ratios of mass differences from microwave measurements are given.

In section d) of Table I, the mass values measured by the flight time of ions in a “chronotron” are presented. For a description of the method and apparatus see, for example, Rick’s book1 on p. 177.

The recalculation of the masses given in the original works to the masses of standards taken from the tables of Dzhelepov and Zyryanova2 was carried out according to the formulas from3 and4. If a given mass \(M\) was compared with the masses of two standards with mass numbers \(A\) and \(B\), whose corrections on transition to the new values are \(\delta A\) and \(\delta B\), then the correction to the mass \(M\), \(\delta M\), is calculated by the formula

\[ \frac{\delta M}{M} = \frac{\delta A}{A}\frac{(M-B)}{(A-B)} + \frac{\delta B}{B}\frac{(M-A)}{(B-A)} . \tag{2} \]

In the case of comparing the mass with three standards with mass numbers \(A\), \(B\), and \(C\), the correction \(\delta M\) for the mass \(M\), caused by the change of the masses of the standards by \(\delta A\), \(\delta B\), and \(\delta C\), is calculated by the formula

\[ \frac{\delta M}{M} = \frac{\delta A}{A}\frac{(M-B)(M-C)}{(A-B)(A-C)} + \frac{\delta B}{B}\frac{(M-A)(M-C)}{(B-A)(B-C)} + \frac{\delta C}{C} \left[ \frac{(M-A)(M-B)}{(B-A)(C-B)} + \frac{(M-B)(M-A)}{(A-B)(C-A)} \right] . \tag{3} \]

In all sections of Table I, not only the results of mass-spectrometric measurements for atoms of medium mass are given, but also the still few published results of measurements of the masses of heavy atoms.

Table II presents all experimentally measured values of the binding energy of the last neutrons in the nuclei of isotopes from scandium through platinum inclusive. The value of the binding energy of the last neutron \(e_n\) can be measured from the energies of the reactions \((\gamma,n)\), \((n,2n)\), \((n,\gamma)\), \((d,p)\), and \((d,t)\). Most measurements were carried out using the reactions \((\gamma,n)\), \((n,\gamma)\), and \((d,p)\); their results are given respectively in columns 3, 4, and 5 of the table. The few measurements using the reaction \((n,2n)\) are placed in column 3 together with the results for the reaction \((\gamma,n)\) and marked by (n). After each figure a reference to the literature is given.

In the case when, in experimental works, the threshold of the reaction \((n,2n)\) is indicated, the reaction energy \(Q\) was calculated by transforming from the laboratory coordinate system to coordinates relative to the center of mass.

The neutron binding energy \(e_n\) was calculated from the energy \(Q\) of the \((d,p)\) reaction by the formula

\[ e_n = Q + E(d), \tag{4} \]

where \(E(d)\) is the binding energy of the deuteron. In accordance with the data of the tables of Dzhelepov and Zyryanova2

\[ E(d)=2.225\pm0.003\ \text{MeV}. \]

In the last column 7, for comparison, values of \(e_n\) are given that are reconciled with all the other data and adopted in Table VI.

Table III gives all data known to the author on the energy of isobaric reactions obtained experimentally. By isobaric we mean reactions in which the initial and final nuclei are isobars; such reactions include \((p,n)\) and \((d,2n)\) reactions.

As in all the other tables of initial data, the last (seventh) column gives, for comparison, values of the difference of the binding energies of the final and initial nuclei, taken from Table VI, i.e., reconciled with all the other data.

Table IV contains data from measurements of the energies of beta particles and gamma quanta. For each number the method of measurement and a literature reference are indicated in parentheses. The method of measurement is denoted by one of three letters: (C)—spectrometric, (P)—by absorption, (K)—with the aid of a Wilson chamber. Before values of gamma-quantum energies corresponding to isomeric transitions, “Is” is written. Isomers in Tables III and IV are marked by an asterisk at the isotope symbol. Of the measurements, only those are given which are not obsolete and can be used for calculating decay energies.

The following designations are adopted for the type of radioactivity: \(\beta^+\), \(\beta^-\)—positron or electron beta decay, respectively; EZ—electron capture; IT—isomeric transition.

In the case of positron decay \((\beta^+)\), columns 6 and 7 give only the sum of the energy of the emitted positron and of the gamma quanta emitted in cascade with it (if any), without adding the pair-creation energy \(2m_e c^2\). Not all data for electron captures are given, but only those among them for which, in one way or another, the EC energy was known or which were needed in compiling Table VI. Data on beta decays are given for the nuclei of all isotopes from potassium through iodine inclusive. For the isotopes from xenon through praseodymium, data on beta decays are given only for the limited number of isotopes that were needed in compiling Table VI.

The last (seventh) column gives the decay energies calculated from the data of Table VI, i.e., reconciled with all other data.

Table V contains experimentally obtained values of the energies of various reactions with medium nuclei, not included in Tables II and III. According to the statements of the authors of the experimental works, all the listed values of reaction energies refer to transitions to the ground state of the daughter nucleus.

In all tables, values given in parentheses were not taken into account in the calculations, since they could not be reconciled with the other data.

Errors in the first columns of all tables of initial data were taken from the original cited works. The errors given in the last columns for the mean values and for the “linked” values, when absent from the original works (i.e., in the first columns of the tables), were found by means of a rough, preliminary estimate. In cases where no error is indicated in the experimental works, then in calculating the weighted mean an error of no less than 5 units of the last significant digit was assigned to these values.

All five tables of initial experimental data were compiled using articles published before January 1, 1954.

II. COMPARISON OF EXPERIMENTAL DATA

The best way to check measurements, making it possible to reveal both random and systematic errors, is to compare their results with the results of other measurements carried out by different methods. In the region of medium stable nuclei, from calcium to xenon, most masses and binding energies can be obtained in several ways, both directly from mass-spectrometric measurements and from the masses of other atoms with the use of reaction energies and beta decays.

For example, the mass of atoms of the isotope $\mathrm{Mn}^{55}$ can be calculated in four ways: 1) from the mass doublet, from the mass of $\mathrm{C}_4\mathrm{H}_7$; 2) from the mass of $\mathrm{Cr}^{54}$ by the reaction $(p,n)$; 3) from the mass of $\mathrm{Fe}^{56}$ by $\beta^{-}$ decay the mass of $\mathrm{Mn}^{56}$ is calculated, and from it, by the neutron binding energy, the mass of $\mathrm{Mn}^{55}$; 4) from the mass of $\mathrm{Fe}^{56}$ the mass of $\mathrm{Fe}^{55}$ is calculated from the neutron binding energy, and from it, by the energy of the reaction $(p,n)$, the mass of $\mathrm{Mn}^{55}$. Even for isotopes for which no mass-spectrometric measurements have yet been made, it is possible to calculate the mass in several ways. Thus, the mass of $\mathrm{Ga}^{71}$ can be calculated in two ways: 1) from the mass of $\mathrm{Zn}^{70}$, using the energy of the reaction $(p,n)$, the mass of $\mathrm{Ga}^{70}$ is calculated, and from it, by the neutron binding energy, the mass of $\mathrm{Ga}^{71}$; or 2) from the mass of $\mathrm{Ge}^{70}$, using the energy of $\beta^{-}$ decay, the mass of $\mathrm{Ga}^{70}$ is calculated, and from it, by the neutron binding energy, the mass of $\mathrm{Ga}^{71}$. Agreement, within the errors, of the masses of $\mathrm{Ga}^{71}$ calculated by both methods confirms the absence of systematic errors in the measurements of the masses of $\mathrm{Zn}^{70}$ and $\mathrm{Ge}^{70}$, in the energy of the beta decay of $\mathrm{Ga}^{70}$, and in the energy of the reaction $\mathrm{Zn}^{70}(p,n)\mathrm{Ga}^{70}$.

Such direct comparison of mass differences measured by different methods has been carried out repeatedly in various works ($^{70,71,171,609}$, etc.). According to the assertion of mass spectrometrists (see, for example, $^{310}$), mass spectrometry is subject to systematic errors, and therefore comparison of mass-spectrometric data with other measurements is especially important.

MASSES OF MEDIUM ATOMS AND BINDING ENERGIES OF THEIR NUCLEI

In one of the most accurate works \(^{71}\) a discrepancy was found between the mass differences \(\mathrm{Cr}^{52} - \mathrm{V}^{51}\), obtained from mass-spectrometric data and from data on nuclear reactions, by an amount exceeding the measurement error. From mass-spectrometric data the mass difference \(\mathrm{Cr}^{52} - \mathrm{V}^{51}\) is equal to \(0.99655 \pm 10\), whereas from reactions this difference was found to be \(0.99738\). However, more accurate measurements \(^{330,397}\) of the \(\beta^-\)-decay of \(\mathrm{V}^{52}\) (see Table IV) led to a change in the value of the mass difference \(\mathrm{Cr}^{52} - \mathrm{V}^{51}\), namely, \(0.99672 \pm 6\), which, within the limits of error, agrees with the mass-spectrometric data. Further, from mass-spectrometric measurements \(^{71}\) the mass difference

\[ \mathrm{Zn}^{64} - \mathrm{Ni}^{64} = 0.00201 \pm 0.00007 \ \text{a.e.m.}, \]

whereas from the difference of the energies of the \(\beta^+\)- and \(\beta^-\)-decay of \(\mathrm{Cu}^{64}\), according to the mean values of Table IV,

\[ \mathrm{Zn}^{64} - \mathrm{Ni}^{64} = 0.001190 \pm 0.000004 \ \text{a.e.m.} \]

The discrepancy thus reaches \(0.00082 \pm 0.00007\) a.e.m. and exceeds the error by more than a factor of 10.

A detailed analysis of this discrepancy was given by Dzhelepov, Zhukovsky, Prikhodtseva, and Kholnov \(^{484}\). They showed that the mass difference \(\mathrm{Zn}^{64} - \mathrm{Ni}^{64}\), if it is calculated from the data of all the other works \(^{101,407,307,302,348,93}\), proves to be larger than that obtained in the most recent and accurate work \(^{71}\), and, consequently, the discrepancies with the beta-decay data become still more significant. An analysis of the decay scheme carried out by Dzhelepov and co-workers shows that there can be no errors or miscalculations in the decay scheme of \(\mathrm{Cu}^{64}\) that would lead to an increase in the mass difference \(\mathrm{Zn}^{64} - \mathrm{Ni}^{64}\). Moreover, the mass difference \(\mathrm{Zn}^{64} - \mathrm{Ni}^{64}\), found from measurements \(^{486,43}\) of the reaction energy \(\mathrm{Ni}^{64}(p,n)\mathrm{Cu}^{64}\) (see Table III), is in full agreement with the positron-decay data. Thus, it should be concluded that this discrepancy is explained by the presence of previously undetected systematic errors in the mass-spectrometric measurements of \(\mathrm{Zn}^{64}\) and \(\mathrm{Ni}^{64}\).

In most other cases, direct comparison of new mass-spectrometric data with measurements of the energies of nuclear reactions and the energies of beta decays, as is seen from comparison of columns 6 and 7 of Tables I, a) and b), indicates the absence of systematic errors. This makes it possible to suppose that the assertion by Dzhelepov and co-workers \(^{71}\) concerning the necessity of a fivefold increase in the mean error of the mass-spectrometric measurements indicated in work \(^{71}\) is considerably exaggerated.

Direct comparison makes it possible to detect discrepancies not only in mass-spectrometric measurements, but also in beta-decay schemes and in reaction energies.

Thus, the decay scheme of Sc⁴⁸, in accordance with works ¹⁸⁹, ²¹⁵, ³¹⁶, ³³⁴, was considered to consist of β⁻ decay to the second excited level of Ti⁴⁸ with subsequent emission of gamma quanta. This corresponded to a mass difference

\[ \mathrm{Sc}^{48}-\mathrm{Ti}^{48}=0.64+1.32+0.99=2.95\ \text{Mev}. \]

Hence, proceeding from the mass-spectrometrically measured ⁷¹ mass values of Ca⁴⁸ and Ti⁴⁸, it followed that the mass difference

\[ \mathrm{Ca}^{48}-\mathrm{Sc}^{48}=1.34\pm0.20\ \text{Mev}. \]

Such a mass difference makes the absence of β⁻ decay of Ca⁴⁸ surprising. Attempts were made ¹⁸⁷ to detect the existence of neutrinoless decay in Ca⁴⁸, but as a result of very careful searches, β⁻ decay of Ca⁴⁸ was not found. This circumstance gave rise to doubts as to the correctness of the β⁻-decay scheme of Sc⁴⁸ proposed in works ¹⁸⁹, ²¹⁵, ³¹⁶, ³³⁴. In this connection, and for other reasons, a check was made ¹⁶⁹, ⁴⁰⁹ of the correctness of the decay scheme of Sc⁴⁸, and from a study of (β-γ) coincidences another decay scheme was proposed. According to the new scheme, the β⁻ decay of Sc⁴⁸ occurs to the third excited level of Ti⁴⁸ with subsequent emission of three gamma quanta with energies 1.05, 1.32 and 0.99 Mev. This scheme leads to the mass difference

\[ \mathrm{Sc}^{48}-\mathrm{Ti}^{48}=0.64+1.05+1.32+0.99=4.00\ \text{Mev}. \]

Which of the two proposed schemes is correct cannot be established without additional data.

The mass of the positron-radioactive isotope Ni⁵⁷ with a half-life of 36 hours can be calculated in two ways: 1) from the mass of Fe⁵⁷, the mass of Co⁵⁷ is calculated from the energy of the positron decay of Co⁵⁷, and from it, from the energy of the positron decay of Ni⁵⁷, the mass of Ni⁵⁷; 2) from the mass of Ni⁵⁸, using the neutron binding energy measured for the (γ, n) reaction (see the corresponding data in Tables II and IV). However, the difference between the values of the mass of the isotope Ni⁵⁷ obtained by these methods is 1.5 ± 0.3 Mev, i.e. five times greater than the permissible error. At the same time, satisfactory agreement of the values of the mass difference Ni⁵⁸—Ni⁵⁷, measured mass-spectrometrically and calculated from nuclear reactions, makes it possible to believe that there are no systematic errors in the mass-spectroscopic measurements. In studying the scheme of the positron decay of Ni⁵⁷, two variants were proposed. According to ¹²³ the energy of the positron decay is

\[ 2.76\pm0.02\ \text{Mev}+2m_e c^2, \]

whereas according to ⁶⁸ it is

\[ 2.21\pm0.01\ \text{Mev}+2m_e c^2. \]

Use of the data of the older work ¹²³ leads to an increase of the discrepancy to

\[ 2.1\pm0.3\ \text{Mev}. \]

Consequently, on the basis of the available data one may assume the existence of an error either in the measurements of the neutron binding energy in the Ni⁵⁷ nucleus, or in the schemes of the positron decays of Ni⁵⁷ or Co⁵⁷. It is not possible to establish by direct comparison in which of the three measurements the error lies.

The mass of the positron-active isotope Ge⁶⁹ with a half-life of 40 hours can be calculated in two ways: 1) from the mass of the stable isotope Ge⁷⁰, using the neutron binding energy obtained from

energies of the (n, 2n) reaction, and 2) from the mass of the stable isotope Ge\(^{69}\) by means of the positron-decay scheme of Ge\(^{69}\) (see the corresponding data in Tables II and IV). The masses of these stable isotopes were measured mass-spectrometrically in work \(^{464}\). The discrepancy in the values of the mass of Ge\(^{69}\) obtained in this way is equal to \(1.0 \pm 0.3\), i.e. it exceeds the possible error by a factor of 3. The mass difference Ge\(^{70}\)—Ga\(^{69}\), known from mass-spectrometric measurements, can also be calculated from reaction energies; in this case the values agree within the limits of error. In addition, the mass of both isotopes can be calculated from reaction energies from the mass of the isotope Zn\(^{70}\). The discrepancy of these values also does not exceed the errors. Thus, one may consider that the initial masses Ga\(^{69}\) and Ge\(^{70}\) are known with sufficient accuracy and have no systematic errors. Consequently, there are errors either in the positron-decay scheme of Ge\(^{69}\), or in the measurement of the energy of the (n, 2n) reaction. Which of these measurements is erroneous cannot be established in this way.

The mass of the radioactive electron-capture isotope Sr\(^{85}\), with a half-life of 65 days, can be calculated from the mass of the stable isotope Kr\(^{84}\) or from the mass of the stable isotope Sr\(^{86}\), measured mass-spectroscopically. By the first method, from the mass of Kr\(^{84}\), using the neutron binding energy measured in the (d, p) reaction, the mass of Kr\(^{85}\) is calculated; from it, using the energy of \(\beta^-\)-decay, the mass of Rb\(^{85}\); and from the latter, using the lower limit of the electron-capture energy, one can find the lower limit of the mass of Sr\(^{85}\). By the second method, from the mass of Sr\(^{86}\), using the neutron binding energy measured in the \((\gamma, n)\) reaction, the mass of Sr\(^{85}\) is calculated directly; it proves to be smaller than the lower limit calculated by the first method by \(2.30 \pm 0.3\) Mev. The discrepancy of the two calculations exceeds the error by almost a factor of 8. The mass of Sr\(^{86}\) is connected with the two other masses Kr\(^{86}\) and Zr\(^{90}\) measured on the mass spectrometer by two chains of decays and reactions. Agreement, within the limits of error, between the mass-spectrometric data and the reaction data makes it possible to speak of the absence of miscalculations or systematic errors in the value of the mass of Sr\(^{86}\). The mass of Kr\(^{84}\), although it cannot be calculated from other masses, nevertheless, judging from the study of the curves, which will be discussed in the following section, has been measured correctly within \(\pm 0.5\) Mэv. Consequently, the only sources of discrepancy in calculating the mass of Sr\(^{85}\) may be substantial errors in the following measurements: in the measurement of the neutron binding energy in Kr\(^{85}\) or in Sr\(^{86}\), and in the schemes of \(\beta^-\)-decay of Kr\(^{85}\) or electron capture in Sr\(^{85}\). Of all these measurements, the most reliable are the measurements of the beta-decay energy of Kr\(^{85}\) (9.4 years) and the lower limit of the electron-capture energy of Sr\(^{85}\) (65 days). Both of these schemes were measured independently in three works each (for Kr\(^{85}\)—in works \(^{503, 504, 583}\), for Sr\(^{85}\)—in works \(^{503, 616, 617}\)), moreover in the pre-

within the limits of possible errors, the results of these works coincide. This makes it possible to regard the decay schemes of \(Kr^{85}\) and \(Sr^{85}\) as quite reliable. Measurements of the reaction energies \(Kr^{84}(d,p)Kr^{85}\) and \(Sr^{86}(\gamma,n)Sr^{85}\) have each been carried out only once, in works \(^{480}\) and \(^{366}\), and there are doubts concerning these measurements. As reported in \(^{480}\), Nier measured the masses of the natural isotopes of rubidium mass-spectrometrically and obtained:

\[ Rb^{85} - 84.93920 \pm 6, \]

\[ Rb^{87} - 86.93709 \pm 17. \]

The value of the mass of \(Rb^{87}\), calculated from the mass of \(Kr^{86}\), the reaction energy \(Kr^{86}(d,p)Kr^{87}\), and the beta-decay energy of \(Kr^{87}\), agrees within the error with Nier’s measurements. The value of the mass of \(Rb^{85}\), however, calculated from the mass of \(Kr^{84}\) from the reaction energy \(Kr^{84}(d,p)Kr^{85}\) and the beta-decay energy of \(Kr^{85}\), differs from Nier’s measurements by 885 kev. The authors of work \(^{480}\) allow that, as a result of the reaction \(Kr^{84}(d,p)Kr^{85}\), the nucleus \(Kr^{85}\) is produced in an excited state with an excess energy of 885 kev. This leads to the supposition that the binding energy of the neutron in the nucleus \(Kr^{85}\) must be equal to \(6.84 \pm 0.05\) Mev. But even in this case, if one calculates the binding energy of the neutron in \(Sr^{86}\), then its lower limit will be greater than the value measured in work \(^{366}\) by \(1.5 \pm 0.3\) Mev. Which of the three variants of the calculation of the mass of \(Sr^{85}\) is correct cannot be established by direct comparison; only the existence of contradictions is clearly seen.

Such are the principal contradictions revealed by direct comparison.

III. COMPARISON AND CHECKING OF EXPERIMENTAL DATA BY THE CURVES OF CROSS SECTIONS OF ENERGY SURFACES

As was established in works \(^{212,550,551}\), a convenient method for analyzing experimental data is the study of energy surfaces. When considering the binding energy \(E\) of nucleons in nuclei as a function of the ordinal number \(Z\) and mass number \(A\), it is found that the binding energy forms four smooth surfaces, separately for even-even, even-odd, odd-even, and odd-odd nuclei (the first parity refers to the number of protons \(Z\), the second parity to the number of neutrons \(A-Z=N\) in the nucleus). Even-even and odd-odd surfaces nowhere intersect either each other or the two other surfaces. Even-odd and odd-even surfaces were previously considered to merge into one, but recently it has been found that they do not coincide, but lie close to one another and may intersect. The smoothness of the course of these surfaces makes it possible to pro-

check by means of them individual unreliable results of measurements of binding energy (by comparing them with other, more reliable ones), and also to find unknown values of the binding energy by interpolation. It is most convenient to consider sections of the energy surfaces by the planes \(Z=\mathrm{const}\) (isotopic section), \(T=A-2Z=N-Z=\mathrm{const}\) (section over nuclei with equal neutron excess), and \(N=\mathrm{const}\) (isoneutronic section). The section \(A=\mathrm{const}\) (isobaric section) is of little use for purposes of interpolation and checking. To reduce the considerable slope of the energy surface, it is recommended to consider a surface with reduced slope of the form \(E_0(A)-E(Z,A)\), where \(E_0(A)\) is some linear function of the mass number \(A\). In particular, for the region of light and medium nuclei one may take

\[ E_0(A)=9A\ \text{MeV}. \]

This auxiliary function considerably reduces the slope of the energy surfaces, since the average slope of the energy surface in this region is close to \(8\ \frac{\text{MeV}}{\text{nucleon}}\).

In a number of papers \(^{610,611,621}\) the author pointed out the existence of the following two regularities in the variation of the binding energies of pairs of protons and pairs of neutrons, valid for all nuclei:

1. The binding energy of the last pair of neutrons increases with the number of protons in the nucleus and decreases with the number of neutrons in the nucleus.

2. The binding energy of the last pair of protons increases with the number of neutrons in the nucleus and decreases with the number of protons in the nucleus.

These regularities make it possible to establish the form of isotopic (\(Z=\mathrm{const}\)) and isoneutronic (\(N=\mathrm{const}\)) sections of the energy surface of binding.

Let us consider the form of the isotopic section (\(Z=\mathrm{const}\)) of the energy surface of binding, constructed according to the equation

\[ f(A,Z)=E_0(A)-E(Z,A), \tag{5} \]

where \(E(Z,A)\) is the binding energy of a nucleus with atomic number \(Z\) and mass number \(A\); \(E_0(A)\) is a linear function of \(A\) of the form

\[ E_0(A)=B+AC \tag{6} \]

(\(B\) and \(C\) are constants). As was indicated, in the region of light and medium nuclei it is expedient to take \(B=0\), \(C=9\ \text{MeV}\). For isotopes of one and the same element, the difference of the binding energies of nuclei of identical parity will be:

\[ E(Z,A)-E(Z,A-2)=e_{2n}(A), \]

where \(e_{2n}(A)\) is the binding energy of the last pair of neutrons in the nucleus with mass number \(A\). It is not difficult to verify that on the isotopic

in a section of the energy surface with reduced slope, according to equation (5), the change in ordinate from nucleus to nucleus will be equal, for scandium isotopes (Fig. 1), to

\[ \Delta E_A = e_{2n}(A) - C. \]

On the basis of the first regularity concerning the change in the binding energy of neutrons, it follows that \(\Delta E_A\) must decrease with increasing \(A\), i.e.,

\[ \Delta E_A > \Delta E_{A+2}. \tag{7} \]

Fig. 1.

Condition (7) leads to the fact that all curves of isotopic sections of the energy surface \(E_0 - E\) must have convexity directed downward, i.e. toward the \(A\)-axis (Fig. 1).

In the same way, on the basis of the second regularity concerning the change in the binding energy of protons, it can be shown that the curves of isotonic sections (\(N=\mathrm{const}\)), represented, for example, in Fig. 2, must likewise have downward convexity, i.e. toward the \(Z\)-axis.

No simple regularities concerning the form of the curves of the sections \(T=\mathrm{const}\) can be indicated, apart from those given above, i.e. that there are no intersections between the even-even and odd-odd surfaces, and also between these two surfaces and the two other surfaces—odd-even and even-odd.

In addition, it should be pointed out that isotopic and isotonic sections of the same parity change only slightly from one value of \(Z\) or \(N\) to the neighboring \(Z \pm 2\) or \(N \pm 2\), preserving a certain similarity, as is seen, for example, from a comparison of Figs. 1, 3, and 6, which contain the sections \(Z=21\), \(Z=23\), and \(Z=25\).

All these regularities and data on the character of the energy surfaces and their sections make it possible to use them for checking individual values of binding energies and for interpolation.

Let us consider several examples.

In Section II it was indicated that for the \(\beta^{-}\)-decay of \(\mathrm{Sc}^{48}\) two decay schemes have been proposed: the first with two gamma quanta and the second with three gamma quanta. For verification we shall consider sections of the energy

surfaces containing the binding energy of the nucleus Sc\(^{48}\). In Fig. 1 the isotopic section of the energy surface with the reduced slope \(E_0 - E\), where \(E_0 = 9A\) MeV and \(E\) is the binding energy of nuclei with plane \(Z = 21\), is presented. The upper curve pertains to odd-odd isotopes of scandium, and the lower one to odd-even isotopes of scandium. Figure 2 shows the isoneutron section \(N = 27\) of the energy surface with reduced slope \(E_0 - E\), containing the binding energy of Sc\(^{48}\). The upper curve pertains to odd-odd nuclei, the lower to even-odd nuclei.

Fig. 2.

In both figures the triangles represent the binding energy of the nucleus Sc\(^{48}\), calculated according to the two-quantum scheme, while the circles represent that calculated according to the three-quantum scheme. The dashed curves drawn through the point obtained from the two-quantum scheme lead to an intersection of the odd-odd surface with surfaces of another parity, which contradicts the properties of the odd-odd surface. The curves drawn through the point obtained from the three-quantum scheme pass in accordance with the known regularities. This leads to the conclusion that the three-quantum scheme is correct for the decay of Sc\(^{48}\). The section \(T = 6\), containing Sc\(^{48}\), gives preference to neither one scheme nor the other, and therefore is not presented here. These conclusions of the author, made jointly with Lemberg \(^{550}\), are also confirmed in an experimental work \(^{553}\).

In connection with this, the supposition arose that the positron decay of V\(^{48}\) also proceeds to the third excited level of Ti\(^{48}\). Figures 3 and 4 give the isotopic section \(Z = 23\) and the isoneutron section \(N = 25\), containing the binding energy of the nucleus V\(^{48}\). Figure 5 shows a section of the energy surface for nuclei with the same neutron excess \(T = 2\). In Fig. 5 the upper curve pertains to odd-odd nuclei, the lower to even-even nuclei. In all three figures the triangles represent points obtained from the three-quantum scheme of the decay of V\(^{48}\), and the circles represent points obtained from the two-quantum scheme of the decay of V\(^{48}\). It follows from Fig. 5 that the dashed curve,

Fig. 3.

Fig. 4.

Fig. 5.

passing through a point belonging to the three-quantum scheme has a completely unjustified protrusion, whereas the solid curve proceeds smoothly in accordance with the even-odd curve. The dashed curve in the isotopic section of Fig. 3 also behaves worse than the solid one, but the main point is that, when considering isotopic sections with \(Z\) equal to 21, 23, and 25 (Figs. 1, 3, and 6), the dashed curve in the section \(Z=23\) (Fig. 3) appears to deviate too far from the odd-even curve in comparison with the sections \(Z=21\) and \(Z=25\) (Figs. 1 and 6). If one compares the isotonic sections of Fig. 2 (\(N=27\)) and Fig. 4 (\(N=25\)), one sees that the dashed curve in Fig. 4 rises too high above the even-odd curve. Consequently, for \(V^{48}\) the two-quantum decay scheme is preferable, which is also confirmed in a number of recent experimental works \(^{334,409,484}\).

Fig. 6.

In Section II, discrepancies were found in the values of the mass and binding energy of the nucleus \(Ni^{57}\), calculated in different ways: from the positron-decay scheme of \(Ni^{57}\) from work \(^{68}\), and from the neutron binding energy in \(Ni^{58}\). Figure 7 shows an isotopic section of the energy surface of nuclei by the plane \(Z=28\). The upper curve refers to even-odd nuclei, and the lower to even-even nuclei. For the isotope \(Ni^{57}\), the point calculated from the positron-decay scheme is marked with a circle, and the point obtained from the measured \((\gamma,n)\)-reaction energy of neutron binding is marked with a triangle. The dashed line intersects the even-even curve and, consequently, does not correspond to the correct arrangement of the energy surfaces. Since the dashed line was drawn on the basis of the measured neutron binding energy, the measurement of the neutron binding energy in \(Ni^{58}\) must be regarded as erroneous. The solid curve is in agreement with the regularities known to us, and therefore the positron-decay scheme of \(Ni^{57}\) established in work \(^{68}\) may be considered correct. Sections of the energy surface by the planes \(N=29\) and \(T=1\) are not given here, since both points

satisfactorily fall on the curves and, consequently, can give nothing new.

Let us next consider which of the values of the binding energies of the nucleus \(Ge^{69}\) corresponds to reality: that calculated from the binding energy

[Figure: graph with vertical axis \((E_0-F)/\text{MeV}\), horizontal axis \(A\), labeled \(Z=28, Ni\).]

Fig. 7.

of the neutron in \(Ge^{70}\), or from the scheme of the positron decay of \(Ge^{69}\). Figure 8 presents the isotopic section of the energy surface by the plane \(Z=32, Ge\). The upper curve corresponds to even-odd

[Figure: graph with vertical axis \((E_0-F)/\text{MeV}\), horizontal axis \(A\), labeled \(Z=32, Ge\).]

nuclei, and the lower one to even-even nuclei. Figure 9 shows a section of the energy surface by the plane \(T=5\), i.e., a section through nuclei with the same excess of five neutrons. In both figures the dashed line represents the curve passing through the point marked by a triangle, for which the energy

Fig. 10.

of the binding energy of \(Ge^{69}\), calculated from the scheme of positron decay of \(Ge^{69}\) proposed in work \(^{166}\). It is quite evident that the dotted curve in Fig. 8 has an inflection, and the convexity has a direction unusual for a \(Z=\mathrm{const}\) curve. From consideration of Fig. 9 it follows that the dotted curve goes worse than the solid one, creating an unjustifiably large deviation of the odd-even curve from the odd-odd one. All this leads to the conclusion that the scheme of positron decay of 40-hour \(Ge^{69}\), proposed in work \(^{166}\), is erroneous. Most probably, the most energetic group of positrons leads mainly to the ground state, and not to the excited state of \(Ga^{69}\). If such an assumption is made, then the discrepancy between the binding energy of the neutron in the \(Ge^{70}\) nucleus and the scheme of positron decay of \(Ge^{69}\) disappears.

Fig. 11.

In Sec. II a contradiction was established between three different ways of calculating the mass of \(Sr^{85}\): 1) from the mass of \(Kr^{84}\), 2) from the mass of \(Sr^{86}\), and 3) from the mass of \(Rb^{85}\). To establish the most reliable data, sections of energy surfaces containing the binding energies of the nuclei \(Kr^{85}\) and \(Sr^{85}\) were studied. Fig. 10 presents an isotopic section at \(Z=36\). The upper curve for even-odd nuclei is drawn in two variants—with a dotted line for the value of the binding energy of \(Kr^{85}\), calculated from the mass of \(Rb^{85}\) measured by Nier, and with a solid line for the value of the binding energy of \(Kr^{85}\), calculated from the \((d,p)\) reaction from the mass of \(Kr^{84}\). The change in the binding energy of \(Kr^{85}\) for the two variants of the curve is due to the fact that

that this energy was obtained by interpolation along the curve and, consequently, depends on the position of the point \(\mathrm{Kr}^{85}\). As is seen from Fig. 10, both variants are acceptable. Fig. 11 shows the isotopic section \(Z=38\). The upper curve has been drawn in three variants: the dotted line with fine dashes is drawn for the value of the binding energy of \(\mathrm{Sr}^{85}\) calculated from the mass of \(\mathrm{Sr}^{86}\) by the energy of the \((\gamma,n)\) reaction; the dotted line with coarse dashes is for the value of the binding energy of \(\mathrm{Sr}^{85}\) calculated from Nier’s mass of \(\mathrm{Rb}^{85}\), and the solid curve is drawn for the binding energy of \(\mathrm{Sr}^{85}\) calculated from the mass of \(\mathrm{Kr}^{84}\) by the energy of the \((d,p)\) reaction and decays. Obviously, the solid curve fits best and the fine dashed line worst. Fig. 12 presents

Fig. 12.

a section, containing the nucleus \(\mathrm{Sr}^{85}\), of the energy surfaces for nuclei in which the neutron excess is \(T=9\). Three variants of curves are drawn with the same designations as in Fig. 11, and here as well, as there, the solid curve fits best and the fine dashed line worst. A final decision can be made from Figs. 13 and 14, where the isoneutron sections are shown, respectively, for \(N=47\) with \(\mathrm{Sr}^{85}\) and \(N=49\) with \(\mathrm{Kr}^{85}\). The curves are given for three and two variants with the same designations as in the preceding figures. From Figs. 13 and 14 it is seen that the results of the calculations, in co-

for which the Nyrop mass of \( \mathrm{Rb}^{85} \) and the reaction energy \( \mathrm{Sr}^{86}(\gamma,n)\mathrm{Sr}^{85} \) are used, are unacceptable, since they lead to curves of an unusual form that contradict known regularities. Thus, the entire set of curves presented indicates the erroneousness of Nyrop’s measurements of the mass of \( \mathrm{Rb}^{85} \) and of the value of the reaction energy \( \mathrm{Sr}^{86}(\gamma,n)\mathrm{Sr}^{85} \), given in work \(^{366}\).

Fig. 13.

Along with the examples given, curves of the sections \(Z=\mathrm{const}\), \(T=\mathrm{const}\), and \(N=\mathrm{const}\) were also used in other cases to confirm or to refute beta-decay schemes and for interpolation.

IV. PROCEDURE FOR CALCULATING NUCLEAR BINDING ENERGIES AND ATOMIC MASSES

The most reliable method for finding probable values of masses, which can be calculated in different ways, is adjustment by the method of least squares. But the method of least squares, so successfully applied by Jezebel and Zyryanova for the masses of light atoms, is disadvantageous for medium nuclei because of the lack of data. The most convenient group of isotopes in the region of medium atoms for applying the method of least squares proved to be the titanium isotope group. Solving the system of normal equations for seven titanium isotopes led to a reduction of the errors by no more than 10%, and therefore in all subsequent calculations the method of least squares was not used. The basis

all the calculations were the values of the masses of stable isotopes, calculated from mass-spectrometric data on the masses of light atoms from the work of Dzhelepov and Zyryanova2. Differences in the mass-spectrometric data were compared with the energies of decays and nuclear reactions. If the discrepancies were within the limits of error, the values were “adjusted,” i.e., the residual was distributed in accordance with the “weights” of the experimental data. If the discrepancy exceeded the error by more than a factor of 2–3, then the experimental data that gave rise to the greatest doubts were discarded. When the source of the errors could not be clarified, comparisons of the data by means of sections of energy surfaces were applied in accordance with Sec. III. The most substantial cases of discrepancies revealed by comparison of the experimental data are given in Sec. II. The most important examples of the application of comparison of experimental data by means of curves are described in Sec. III.

The results of these calculations gave adjusted values of the masses of atoms and binding energies of their nuclei for the majority of stable and some neighboring “central” isotopes of the elements from calcium to molybdenum and from rhodium to xenon. The masses of the central isotopes from molybdenum to ruthenium could not be checked by comparison because of the lack of experimental data. This region has the largest errors and is the least reliable. In particular, most of the masses of the stable isotopes of ruthenium were obtained by interpolation along the curves. The masses of “extreme” isotopes, i.e., isotopes with a large deficiency or a large excess of neutrons, were found from the masses of the “central” isotopes, as a rule, from beta-decay energies and sometimes from the energies of \((p, n)\)-reactions. The masses of the extreme isotopes are less reliable, since they are based sometimes on only a single and not always reliable measurement. To check the masses of extreme isotopes, curves of sections of energy surfaces by the planes \(Z = \mathrm{const}\), \(N = \mathrm{const}\), and \(T = \mathrm{const}\) were widely used. In cases where points fell off the curves, attempts were made, on the basis of the available measurements of the energies of particles and gamma quanta, to construct a new scheme that would give a binding energy satisfactorily lying on all the curves of the three sections mentioned. Such a case is described in Sec. III in the example with the positron-decay scheme of 40-hour \(\mathrm{Ge}^{69}\). In the same way the beta-decay scheme of 36-hour \(\mathrm{Br}^{82}\) was changed, and beta-decay schemes were compiled for 8-minute \(\mathrm{Ca}^{49}\), 4-hour \(\mathrm{Y}^{92}\), 16-minute \(\mathrm{Y}^{84}\), 65-day \(\mathrm{Zr}^{95}\), and others.

In the event that a satisfactory new scheme could not be compiled, while the existing scheme gave a value falling off the curves, or if in general there were no data for calculating the binding energy and mass, the binding energy of the given nucleus was determined by interpolation along the curves. In doing so, wherever possible the curves of all three sections were used. In this way, for example, the binding energies of nuclei and, from them, the masses of the atoms of the following

isotopes: \(Ca^{46}\), \(Sc^{42}\), \(Sr^{84}\), \(Mo^{93}\), \(Ru^{98}\), \(Ru^{99}\), \(Ru^{100}\), etc. Sometimes such interpolation was carried out simultaneously for groups of isobars connected by beta-decay energies, for example: \(Ga^{73}\) and \(Ge^{73}\); \(Kr^{82}\) and \(Rb^{81}\); \(Ru^{101}\), \(Tc^{101}\), and \(Mo^{101}\), and others.

The results of all the calculations are presented in Table VI. The meaning of most of the columns of Table VI is clear from the headings. It should be recalled that the binding energy of nucleons, given in column 7, \(E(Z,A)\), in a nucleus with atomic number \(Z\) and mass number \(A\), is related to the atomic mass \(M(Z,A)\) by the following relation:

\[ E(Z,A)=Zm_{\mathrm H}-(A-Z)m_n-M(Z,A), \tag{8} \]

where \(m_{\mathrm H}\) is the mass of the hydrogen atom, and \(m_n\) is the mass of the neutron.

In converting the atomic mass unit (a.m.u.), equal to \(1/16\) of the mass of the neutral atom of the oxygen isotope with mass number 16, it was assumed that \(1\) a.m.u. \(=931.152\) MeV.

Column 8 of Table VI gives references to the sources of data for calculating the binding energy of each of the nuclei (or the atomic mass). The purpose of this column is to make it possible to reconstruct the course of the calculations by which the binding energy of any nucleus or atomic mass was obtained. First, the isotope is indicated from whose binding energy the binding energy of the given isotope was calculated. The Roman numeral following it in parentheses indicates from which table of initial experimental values the energy or mass difference was taken for calculating the binding energy of the given nucleus. Thus, for example, from column 8 it can be established that the binding energy of the nucleus of the isotope \(Sc^{48}\) was obtained by calculation from the binding energy of the \(Ti^{48}\) nucleus using beta-decay energies taken from Table IV, or that the atomic mass of the isotope \(Sc^{46}\) was calculated from the mass of the molecule \(C_2O_2H_5\), using the mass difference of the doublet given in Table I, a). In column 8 the following abbreviations are used:

interp. — the binding energy was obtained by interpolation along curves (see § III); (ls) — in balancing binding energies the method of least squares was used.

For the central isotopes, the nuclear binding energies of which were calculated in different ways, all these ways are indicated in column 8. The nuclear binding energies and atomic masses of these isotopes are weighted averages of several values and, consequently, are more reliable. For example, the nuclear binding energy and atomic mass of the stable isotope \(V^{51}\) were obtained by three methods: 1) from the mass doublet [Table I, a)] from the mass of the molecule \(C_4H_3\); 2) from the neutron binding energy (Table II) from the binding energy of \(V^{52}\); 3) from the energy of \((p,n)\)-reactions (Table III) from the binding energy of \(Cr^{51}\). The results given in columns 6 and 7 are weighted averages of the mass and binding energy values calculated by these three routes. Thus, column 8 of Table VI makes it possible to establi...

MASSES OF MEDIUM ATOMS AND BINDING ENERGIES OF THEIR NUCLEI

a way of obtaining the masses and binding energies given in Table VI, and, in the event that new experimental data appear, to use them for refining the values.

The errors of the atomic masses and binding energies were calculated by the well-known formula for the error of a sum and a difference, namely:

\[ \sigma=\sqrt{\sigma_0^2+\sigma_1^2+\sigma_2^2+\ldots+\sigma_i^2}, \tag{9} \]

where \(\sigma_1,\sigma_2,\ldots,\sigma_i\) are the errors of all \(i\) links of the experimental quantities, taken from the tables of initial data, and \(\sigma_0\) is the error of the mass taken from the tables of Dzhelepov and Zyryanova\(^{104}\). The errors of the masses in column 6 are given in units of the last significant digit of the mass.

A satisfactory estimate of the errors given in the tables is confirmed by the fact that the appearance of new measurements in the course of compiling Table VI and the recalculation of the masses caused by them always changed the masses by an amount smaller than the established error.

For isotopes with atomic number greater than 54, beginning with barium, mass-spectrometric measurements are still fragmentary in character, and at present it is impossible to compile detailed tables of masses in this region. The masses of individual atoms and the binding energies of nuclei heavier than xenon are given in Table VII. The values of the atomic masses given in Table VII were obtained mainly from the mass-spectrometric data of Table I [sections a) and b)], with the use, in individual cases, of the neutron binding energy from Table II and, very rarely, of beta-decay energies from Table IV. The paths of the calculation can be reconstructed from column 7 of Table VII. In this region, checking by curves is impossible because of the small number of binding energies; checking the masses by comparison is possible only for the isotopes of platinum and lead. Therefore, for atoms with mass less than 190, undetected systematic errors and miscalculations exceeding the errors are possible, though their probability in Table VI is very small.

In the tables of binding energies of heavy nuclei\(^{212}\) published by the author, the binding energies of the isotopes of lead, thorium, and uranium disagree with the data of Table VII, since they were calculated according to the old standards. To convert to the new standards it is necessary to correct all masses greater than 197 and the corresponding binding energies: add 1.76 MeV to the binding energies, and subtract 0.00124 a.m.u. from the masses. After correction, the data\(^{212}\) can be compared with the present tables and with the tables\(^{104}\).

In conclusion, I consider it my pleasant duty to express gratitude to B. S. Dzhelepov and L. N. Zyryanova for communicating data from their tables before their publication, and also to my son A. V. Kravtsov for assistance in the calculations.
