New Results from the NEMO 3 Experiment

Nuclear Experiment 2019-08-13 v1

Abstract

NEMO 3 is a currently running experiment to search for the neutrinoless double beta decay and to study the two-neutrino double beta decay with 10kg of enriched isotopes. On the basis of the first two years of data taking, a limit on the neutrinoless decay T1/20ν>5.81023T_{1/2}^{0\nu} > 5.8\cdot10^{23} y at 90% CL was obtained with 100Mo^{100}Mo. The two-neutrino double beta decay half-lives were measured for all seven ββ\beta\beta isotopes located in NEMO 3. New results are obtained for two of these isotopes: 48CaT1/22ν=[4.40.4+0.5(stat)±0.4(syst)]1019^{48}Ca T_{1/2}^{2\nu}=[4.4 ^{+0.5}_{-0.4} (stat) \pm 0.4 (syst)]\cdot10^{19} y, 96ZrT1/22ν=[2.3±0.2(stat)±0.3(syst)]1019^{96}Zr T_{1/2}^{2\nu}=[2.3 \pm 0.2 (stat) \pm 0.3 (syst)]\cdot10^{19} y.
