Abstract

In this study, we investigate the two-neutrino double-beta decay (2νββ) of 82Se to the first excited 0+ 2 state of 82Kr within the framework of the nuclear shell model. We consider four different interactions and we analyze the validity of these interactions in reproducing the experimental properties of the initial and final states of the decay. The calculated half-life for the decay is determined using as reference the comparison between the calculated decay of 82Se to the ground state of 82Kr and experimental data. We find an interval for the predicted half-life for this transition that is T2ν1/2(82Se, 0+gs → 0+2 ) = (3.5 − 170) · 1022 yr.
