Abstract
All existing positive results on two-neutrino double beta decay in different nuclei were analyzed. Using the procedure recommended by the Particle Data Group, weighted average values for half-lives of 48Ca, 76Ge, 82Se, 96Zr, 100Mo, 100Mo–100Ru (01+), 116Cd, 130Te, 136Xe, 150Nd, 150Nd–150Sm (01+) and 238U were obtained. Existing geochemical data were analyzed and recommended values for half-lives of 128Te and 130Ba are proposed. Given the measured half-life values, nuclear matrix elements were calculated using latest (more reliable and precise) values for phase space factor. Finally, previous results (PRC 81 (2010) 035501) were updated and results for 136Xe were added.
