Description
A lower limit of 1.16 x 1023 yr (1sigma) is reported for the half-life of no-neutrino β-β- decay of 76Ge which results from 3763 h of counting with an ultralow-background, 135-cm3 prototype detector located 1438 m underground. A limit of 1.7 x 1023 yr (1sigma) results from the best combination of our data with that from other experiments. Straightforward application of shell-model matrix elements to this limit implies that <3.2 eV (1sigma)
