Abstract

AbstractWe report the measurement of the two-neutrino double-beta (

$$2\nu \beta \beta $$

2νββ) decay of

$$^{100}$$

100Mo to the ground state of

$$^{100}$$

100Ru using lithium molybdate (

$$\hbox {Li}_2^{\;\;100}\hbox {MoO}_4$$

Li2100MoO4) 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

$$\times $$

×day, the half-life of

$$^{100}$$

100Mo is determined to be

$$T_{1/2}^{2\nu }=[7.12^{+0.18}_{-0.14}\,\mathrm {(stat.)}\pm 0.10\,\mathrm {(syst.)}]\times 10^{18}$$
