TABLE OF ATOMIC NUCLEI

B. Dzhelepov and S. Petrovich

In view of the fact that tables of nuclear constants published in handbooks become obsolete relatively quickly, it seems expedient to publish new data periodically. The present table, owing to the limited space in the journal, cannot duplicate large reference monographs, in which a complete bibliography is given. Therefore it gives references only to works published during the past year.

A summary of various values and a complete bibliography may be found in reference monographs on the physics of the atomic nucleus (G. T. Seaborg and I. Perlman, Reviews of Modern Physics 20, No. 4 (1948). I. Mattauch und A. Flammersfeld, Isotopenbericht, Verlag der Zeitschrift für Naturforschung, Tübingen, 1949).

The present table gives a complete list of all stable and radioactive isotopes and a summary of their most important properties according to data published up to January 1, 1950.

In the first column the atomic number is given.

In the second column are listed the stable isotopes of elements with \(Z < 84\); in the third column—the \(\beta\)-radioactive nuclei (we include in this concept both \(\beta^-\)- and \(\beta^+\)-active nuclei, as well as nuclei that capture atomic electrons) and nuclear isomers of both stable and radioactive nuclei.

After bismuth (\(Z > 83\)) there are no stable nuclei: all nuclei are either \(\alpha\)- or \(\beta\)-radioactive.

In this region the division of nuclei between the second and third columns has been made according to a new principle: in the second column are placed those \(\alpha\)-radioactive nuclei for which, on the basis of the regularity of the construction of the Pleiades, no \(\beta\)-processes can be expected.

In the third column are placed the remaining nuclei, irrespective of whether β-decay has been observed for them experimentally or only α-decay is so far known.

In parentheses are placed the mass numbers of isotopes if they are not reliable, or if one of the two indicated values is possible. When the element is unreliable or the isotope is doubtful, the entire symbol of the nucleus is placed in parentheses. Isomeric nuclei are marked with a circle with a dot, ⊙.

In the fourth column is given the relative abundance of the isotopes, in percent of the total number of all atoms of the given element.

In the fifth column the half-lives are given. The letters following the numerals denote: г and л — years, д — days, ч — hours, м — minutes, с — seconds, мкс — microseconds.

In the sixth column the type of transformation of the nucleus is given, with the following designations:

α — alpha decay of the nucleus,
β− — transformation with emission of a negatively charged electron,
β+ — emission of a positron (positive electron),
K — transformation with capture of an electron from the K-shell of the atom,
L — transformation with capture of an electron from the L-shell of the atom,
I — isomeric transition (transition from an upper energy state to a lower one),
2β− — emission of two electrons simultaneously.

In those cases where the emission of neutrons follows β-decay, we have placed the information on neutrons in one line with β-decay; although in reality the neutron is emitted by the nucleus that is the product of β-decay, it is customary to speak of “delayed neutrons,” assigning to them the decay period of the parent.

In those cases where there is more than one type of transformation and the nucleus can decay alternatively by one method or another, the corresponding designations of the decay types are separated by a comma.

In the seventh column are given the energies of α- and β-particles. For α-radioactive isotopes, the energy values and (in parentheses) the relative intensities of the individual groups are given. For β-particles, besides the limiting energy, there is indicated in percent, in those cases where this is possible, the fraction of all β-particles constituted by the given group. (We note that this quantity is not the fraction of all decays; the latter quantity in most cases of β+-decays cannot be estimated until K-capture has been investigated.)

In the eighth column are indicated the energy values of γ-quanta or the corresponding level differences in those cases where γ-rays ...

fully converted. In addition to the energy of the $\gamma$-rays, in those cases where this is possible, the number of quanta per decay is indicated in percent. In those cases where only the relative intensities of the $\gamma$-lines are known, but their participation in the decay is unknown, the corresponding values are given in parentheses without the percent sign. Annihilation gamma rays are not noted. For half-lives and the energies of $\alpha$- and $\beta$-particles and $\gamma$-quanta, as a rule, one most reliable value is given. In those cases where values obtained by different authors are approximately equivalent and it is not possible to indicate the more probable one, the mean value is given, marked with an asterisk (*). Doubtful data are enclosed in parentheses.

In the last, ninth, column are placed the nuclear reactions by which the radioactive nucleus is obtained. The reactions are written in the following sequence: initial nucleus, incident particle, and resulting particle (or particles). The particles are denoted as follows: $\alpha$ — alpha particle, $t$ — triton, $d$ — deuteron, $p$ — proton, $n$ — neutron, $\gamma$ — gamma rays, $x$ — X-rays. Fission of a nucleus is denoted by a crossed circle $\oplus$.

When a nucleus (e.g. $\mathrm{Te}^{133}$) is formed from another nucleus obtained as a result of fission, the reaction is written as follows:

\[ \mathrm{U}(n,\oplus)\,\mathrm{Sb}^{133}\ (10\ \mathrm{m})\ \beta^-, \]

and for a nucleus (e.g. $\mathrm{Sb}^{133}$) that is the primary product of fission, the reaction is written thus:

\[ \mathrm{U}—n—\oplus. \]

In those cases where the nucleus is obtained as the result of a chain of successive radioactive transformations, only the initial nucleus and the nucleus preceding the given one are indicated. Intermediate radioactive nuclei are not indicated.

In reactions with the emission of a large number of protons and neutrons, these particles are placed in square brackets, since in this case the emission of complex particles ($\alpha$, $d$, etc.) and intermediate radioactive transformations are also possible.

When it is not reliably known from which initial nucleus a radioactive isotope is obtained, the corresponding mass number of the initial nucleus is placed in parentheses. If the number of emitted particles or the type of reaction is uncertain, parentheses or a question mark are likewise used.

Data obtained in 1949 are given in full. After the corresponding value in square brackets a reference to the literature is indicated.

The literature, in accordance with the generally accepted notation (for analogous tables), is given in alphabetical order (by the first letter).
