The first large-scale shell-model calculation of the two-neutrino double beta decay of 76Ge to the excited states in 76Se

Large-scale shell-model calculations were carried out for the half-lives and branching ratios of the 2νββ decay of 76Ge to the ground state and the lowest three excited states 21+, 02+ and 22+ in 76Se. In total, the wave functions of more than 10,000 intermediate 1+ states in 76As were calculated in...
