We report the measurement of the two-neutrino double-beta (2) decay of 100Mo to the ground state of 100Ru using lithium molybdate (Li1002MoO4) scintillating bolometers. The detectors were developed for the CUPID-Mo program and operated at the EDELWEISS-III low background facility in the Modane underground laboratory (France). From a total exposure of 42.235 kg×day, the half-life of 100Mo is determined to be 21/2=[7.12+0.18−0.14(stat.)±0.10(syst.)]×1018 years. This is the most accurate determination of the 2 half-life of 100Mo to date.

Abstract
We report the measurement of the two-neutrino double-beta (2) decay of 100Mo to the ground state of 100Ru using lithium molybdate (Li1002MoO4) scintillating bolometers. The detectors were developed for the CUPID-Mo program and operated at the EDELWEISS-III low background facility in the Modane underground laboratory (France). From a total exposure of 42.235 kg×day, the half-life of 100Mo is determined to be 21/2=[7.12+0.18−0.14(stat.)±0.10(syst.)]×1018 years. This is the most accurate determination of the 2 half-life of 100Mo to date.File in questo prodotto:
