Abstract

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+eK 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.
