摘要：

We study the two-neutrino double-beta. decay in Ge-76, Cd-116, Te-128, Te-130, and Nd-150, as well as the two Gamow-Teller branches that connect the double-beta. decay partners with the states in the intermediate nuclei. We use a theoretical microscopic approach based on a deformed self-consistent mean field with Skyrme interactions including pairing and spin-isospin residual forces, which are treated in a proton-neutron quasiparticle random-phase approximation. We compare our results for Gamow-Teller strength distributions with experimental information obtained fromcharge-exchange reactions. We also compare our results for the two-neutrino double beta decay nuclear matrix elements with those extracted from the measured half-lives. Both single-state and low-lying-state dominance hypotheses are analyzed theoretically and experimentally making use of recent data from charge-exchange reactions and beta decay of the intermediate nuclei.
