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