摘要：

A method to calculate the two-neutrino double beta decay (2nubetabeta) to one-phonon excited states is presented. The formalism, which is based on the quasiparticle random phase approximation, is applied to the description of the 2nubetabeta transition Xe-136 (0(g.s.+) --> Ba-136(2(1)+). It is shown that the participant matrix element is not suppressed by the inclusion of renormalized particle-particle interactions.
