Double beta decays of ¹⁰⁰Mo and charge nonconserving excitations of ¹²⁷I

Double beta ( beta beta ) decays of ¹⁰⁰Mo and charge nonconserving excitations of ¹²⁷I were studied by means of ELEGANTS V. A finite half-life of T₁2/^{2 nu} =1.15_-0.20^+0.30*10¹⁹ y (68% CL) for the two neutrino beta beta decay of ¹⁰⁰Mo and the most stringent lower limit of T₁2/^{0 nu} >4.7*10²¹ y (68% CL) on the half-life for the neutrinoless beta beta decay of ¹⁰⁰Mo were obtained. Lower limits on the mean life of the charge nonconserving (CNC) processes ¹²⁷I+e_K to ¹²⁷I*+ nu leading to the first excited states of ¹²⁷I were obtained as tau >1.1*10²³ y by searching for the gamma decay.
