Neutrino Mass from the Beta Spectrum in the Decay of Tritium

The data from the spectrum measurement of the tritium decay in a valine molecule carried out in a wide energy range (3.4 KeV) with the ITEP spectrometer are analyzed. The combined analysis of both these data and the data of the previous cycle gives the neutrino mass 30.3/sub -8//sup +2/ eV. The model-independent mass interval 17
