摘要：

The renormalized proton-neutron quasiparticle random-phase approximation model (RQRPA) has been used to calculate double-beta-decay matrix elements and associated transition half-lives for two-neutrino double beta decay of parent nuclei Ge-76, Kr-78, Se-82, Zr-96, Cd-106, and Te-130 to the ground state and excited one- and two-phonon states of their daughter nuclei. The results are compared to ordinary proton-neutron QRPA and experiments. In addition, the violation of the Ikeda sum rule in the RQRPA is examined and discussed.
