Abstract

A lower limit of 1.16×1023 yr (1σ) is reported for the half-life of no-neutrino ββ decay of Ge76 which results from 3763 h of counting with an ultralow-background, 135-cm3 prototype detector located 1438 m underground. A limit of 1.7×1023 yr (1σ) 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 mν<3.2 eV (1σ).
