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, 150Nd, 150Nd− 150Sm(01+) and 238U were obtained. Existing geochemical data were analyzed and recommended values for half-lives of 128Te, 130Te, and 130Ba are proposed. We recommend the use of these results as presently the most precise and reliable values for half-lives.
