Abstract
The results of the “Troitsk ν-mass” experiment on the search for the neutrino rest mass in tritium beta decay are presented. The investigation of the time dependence of the anomalous, bumplike structure at the end of the beta spectrum, reported earlier, gives an indication of the periodic shift of its position with respect to the endpoint with a period of 0.5 yr. An upper limit on the electron-antineutrino rest mass (m νc 2) is derived after taking the bump into account.Keywords
