In my article (Yu. V. Shaldin, “Experimental detection of electric gyrotropy in SrMoO₄ crystals”), published in DAN, vol. 191, no. 1, 1970, p. 68, the final formula for calculating the component \(\alpha'_{333}\) was printed as

\[ \alpha'_{333}=\frac{\lambda_0^2 n_0^2}{2\pi^2}\,\frac{\operatorname{tg}\alpha}{v_{=}}, \]

it should read

\[ \alpha'_{333}=\frac{\lambda_0^2}{4\pi^2 n_0^3}\,\frac{\operatorname{tg}\alpha}{v_{=}}, \]

which, in the final calculation during the processing of the experimental data, led only to an overestimated value for the tensor component \(\alpha'_{333}\), which has now proved to be equal to \(1\cdot 10^{-16}\ \text{cm}^2/\text{V}\).

ERRATUM

In our article (E. E. Berlovich, Yu. N. Novikov, “On the probability of double beta decay of nuclei in regions far from the beta-stability band”), published in DAN, vol. 188, no. 5, 1969, p. 1024, Fig. 1B, instead of the values of scale divisions along the ordinate axis \(10^{-11}, 10^{-13}, 10^{-15}, 10^{-17}, 10^{-19}\), the values should be \(10^{-8}, 10^{-10}, 10^{-12}, 10^{-14}, 10^{-16}\), respectively.
