Abstract
Results of the “Troitsk ν-mass” experiment on the search for the neutrino rest mass in the tritium beta-decay are presented. Study of time dependence of anomalous, bump-like structure at the end of beta spectrum reported earlier gives indication of periodic shift of the position of the bump with respect to the end-point energy with a period of 0.5 year. A new upper limit for electron antineutrino rest mass mν<2.5 eV/c2 95% C.L. is derived after accounting for the bump.
