Description

Two neutrino double beta (2νββ ) Gamow-Teller transitions, 0i+ → 0f+ and 0i+ → 2f+ are treated with a many-body Hamiltonian involving a Bonn-type realistic two-body interaction. The states involved in these transitions are described by a pnRQRPA approach. Transition operators are expanded in first order in terms of renormalized bosons. For illustration the formalism is applied to the case 82Se → 82Kr. (author)
