New limits on the beta+ EC and ECEC processes in 120Te
Résumé
New limits on the double beta processes for 120Te have been obtained using a 400 cm3 HPGe detector and a source consisting of natural Te0_2 powder. At a confidence level of 90% the limits are 0.19times 10^8y for the beta EC(0\nu + 2\nu) transition to the ground state, 0.75times 10^18 y for the ECEC(0\nu + 2\nu)transition to the first 2+excited state of 120Sn (1171.26 keV) and (0.19-0.6)\times 10^18 y for different ECEC(0\nu captures to the ground state of 120Sn.
