Abstract
A new lower limit of 3.2× yr has been obtained for the half-life of neutrinoless double decay of to the ground state of , by use of a Ge detector of 208 active volume running in a salt mine for 2363 h. This is the largest detector used to date in such an experiment. A limit for decay to the first excited state has also been obtained.
