摘要：
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-live of Ca-48, Ge-76, Se-82, Zr-96, Mo-100, Mo-100-Ru-100(O-1(+)), Cd-116, Nd-150, Nd-150-Sm-150(0(1)(+)) and U-238 were obtained. Existing geochemical data were analyzed and recommended values for half-lives of Te-128, Te-130, and Ba-130 are proposed. We recommend the use of these results as presently the most precise and reliable values for half-lives.
