摘要：
New experimental limits for the decay e- --> gamma + nu(e) are reported. The lower limit for the half-life of this decay mode is T1/2e > 1.63 x 10(25) yr (68% CL). The data were collected for 3199 h by using one of the enriched germanium detectors of the Heidelberg-Moscow betabeta Collaboration. This detector has an active volume of 591 cm3. This value is up to now the most stringent laboratory limit for this decay mode. Also charge nonconservation in nuclei is shortly discussed in the Ga-Ge system using the data of gallium solar neutrino experiments.
