Abstract

A set of two natural abundance Ge detectors of 1.1 kg each, located in the Homestake mine, and one small, 0.253 kg, Ge detector operating in the Canfranc railway tunnel in Spain, have been used to obtain bounds on the stability of the electron against the decay modes e- → γνe and e- → νeνeνe. The bounds on the mean lifes are τ(γνe) > 3.7(2.1) × 1025 yr, 68%(90%) CL and τ(νeνeνe > 4.3(2.6) × 1023 yr, 68%(90%) CL, which are at present the most stringent laboratory limits for these decays.
