Abstract

All existing positive results on two-neutrino double beta decay and two-neutrino double electron capture in different nuclei have been analyzed. Weighted average and recommended half-life values for $^{48}$ Ca, $^{76}$ Ge, $^{82}$ Se, $^{96}$ Zr, $^{100}$ Mo, $^{100}$ Mo - $^{100}$ Ru ( $0^+_1$ ), $^{116}$ Cd, $^{128}$ Te, $^{130}$ Te, $^{136}$ Xe, $^{150}$ Nd, $^{150}$ Nd - $^{150}$ Sm ( $0^+_1$ ), $^{238}$ U, $^{78}$ Kr, $^{124}$ Xe and $^{130}$ Ba have been obtained. Given the measured half-life values, effective nuclear matrix elements for all these transitions were calculated.
