| Popis: | The β -spectrum of 35 S has been measured with high statistical precision. A total of 2.2×10 10 events have been accumulated with a signal to background ratio of 10 3 or better. A systematic search for neutrino mixing has been performed for assumed neutrino masses up to 105 keV. In the mass range 10 to 90 keV, an upper limit around 10 −3 or less was set for the mixing probability. |
