Abstract

Studies of the 2β decay of 116Cd, 180W and 186W have been performed in the Solotvina Underground Laboratory with the help of the super-low background 116CdWO4 crystal scintillators. The half-life value of the two-neutrino 2β decay of 116Cd has been revised as T1/22ν=2.9±0.1(stat)−0.3+0.4(syst)×1019 yr. Besides, the new half-live limits on different modes of this process have been established for two natural tungsten isotopes, in particular, T1/2≥1.0 (1.6)×1021 yr at 90% (68%) C.L. for the neutrinoless 2β decay of 186W to the ground (0+) and first excited (2+) level of 186Os.
