Abstract: All existing ``positive- results on two neutrino double beta decay indifferent nuclei were analyzed. Using the procedure recommended by the ParticleData Group, weighted average values for half-lives of $^{48}$Ca, $^{76}$Ge,$^{82}$Se, $^{96}$Zr, $^{100}$Mo, $^{100}$Mo - $^{100}$Ru $0^+ 1$,$^{116}$Cd, $^{130}$Te, $^{150}$Nd, $^{150}$Nd - $^{150}$Sm $0^+ 1$ and$^{238}$U were obtained. Existing geochemical data were analyzed andrecommended values for half-lives of $^{128}$Te, $^{130}$Te and $^{130}$Ba areproposed. We recommend the use of these results as presently the most preciseand reliable values for half-lives.
