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 {sup 76}Ge, {sup 78}Kr, {sup 82}Se, {sup 96}Zr, {sup 106}Cd, and {sup 130}Te 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. {copyright} {ital 1997} {ital The American Physical Society}
