Negatron decay of 122Sb

A unique set of numerical values for six nuclear matrix elements, ∫sigma.r, ∫γ5, ∫r, ∫α, ∫sigma x r and ∫Bsub(ij), were found by means of the chi-square fit to the experimental data on the beta-ray spectrum and beta-gamma directional correlation in the cascade transition, 2-(1.4 MeV β-)2+(0.56 MeV γ)0+ of 122Sb, measured by Yamada and Hayashi. These matrix elements are also consistent with all other available data on this transition. (auth.)
