Description
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 (0+1 ), 116Cd, 130Te, 136Xe, 150Nd, 150Nd– 150Sm (0+1 ) and 238U have been obtained. Existing geochemical data were analyzed and recommended values for half-lives of 128Te and 130Ba are proposed. Finally, previous results [NPA 935 (2015) 52)] were updated. Situation with 78Kr result is discussed.
