In my article (Yu. V. Shaldin, “Experimental detection of electric gyrotropy in $\mathrm{SrMoO}_4$ crystals”), published in Doklady Akademii Nauk, 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 analysis during processing of the experimental data, led only to an overestimated value for the tensor component $\alpha'_{333}$, which has now turned out to be equal to $1\cdot 10^{-16}\ \mathrm{cm}^2/\mathrm{V}$.

ERRATUM

In our article (E. E. Berlovich, Yu. N. Novikov, “On the probability of double beta decay of nuclei in regions remote from the beta-stability band”), published in Doklady Akademii Nauk, vol. 188, no. 5, 1969, p. 1024, Fig. 1B, instead of the scale values of the points on 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.
