Popis:	The end-point region of the β-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 mν2 = − 22 ± 4.8 eV2 / c4. It is shown that the negative mν2 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 mν
