Abstract
All existing positive results on two-neutrino double- decay in different nuclei were analyzed. Using the procedure recommended by the Particle Data Group, weighted average values for half-lives of , , , , , - (), , , , - (), and were obtained. Existing geochemical data were analyzed, and recommended values for half-lives of , , and are proposed. Given the measured half-life values, nuclear matrix elements were calculated. I recommend the use of these results as the most currently reliable values for the half-lives and nuclear matrix elements.
