| dc.description | Two-neutrino double-beta (2νββ) Gamow-Teller transitions, 0<sup>+</sup><sub>i</sub>→0<sup>+</sup><sub>f</sub> and 0<sup>+</sup><sub>i</sub>→2<sup>+</sup><sub>f</sub>, 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. In this way the space of intermediate states is enlarged due to the states with two and three bosons. Important effects on both transition amplitudes and Ikeda sum rule are pointed out. For illustration the formalism is applied to the transition <sup>82</sup>Se→<sup>82</sup>Kr. |
