Popis:	The endpoint region of the tritium β-spectrum has been measured with 27 eV resolution, using a magnetic spectrometer. The tritium activity was implanted into a thin layer of carbon. The neutrino mass determined is consistent with zero with an upper limit of 18 eV/c2, which includes instrumental and statistical uncertainties as well as uncertainties due to energy loss in the source and the final electronic states. This result is in contradiction to the finite mass of 30 eV/c2 reported by the ITEP-group. In the discussion a review of the present status of the various tritium experiments is given.
