Description

The low energy nuclear beta or electron capture (EC) decays are excellent tools for testing non-zero neutrino masses. Among all beta unstable nuclides, ${}^3$H, ${}^{187}$Re, and ${}^{163}$Ho are attractive for non-zero neutrino mass experiment due to their low Q-values. The EC decay of the isotope ${}^{163}$Ho has been proposed since a long time as a candidate for measuring the electron neutrino mass and the interest in ${}^{163}$Ho has been renewed because of a possible relic antineutrino capture experiment. But if there is no overdensity in the $\nu$ distribution, the detection using ${}^{163}$Ho is not possible. In this talk, we will present new possible candidates for relic anti-neutrino capture experiments using EC decaying nuclei.
