摘要：

We report on two high statistics measurements of the beta spectrum of S-35. Particular emphasis is given to the sensitivity of results on details of the electron response function. In both measurements we find an 8 standard deviation from the single component neutrino spectrum 17 keV below the endpoint. The data are in strong support of earlier claims that the neutrino emitted in beta decay contains a 17 keV mass component with a mixing probability given by sin2-theta = 0.0084 +/- 0.0006 +/- 0.0005.
