摘要：

The end-point region of the P-spectrum of tritium has been measured with an integral electrostatic spectrometer with adiabatic magnetic collimation and gaseous tritium source. The search for the neutrino rest mass has resulted in m(v)(2) = -22 +/- 4.8 eV(2)/c(4). It is shown that the negative m(v)(2) effect may be explained by the local enhancement in the region 7-15 eV below the end point with an integral B.R. of about 10(-10). After accounting for this anomaly one is able to deduce that m(v) < 4.35 eV at 95% C.L.
