摘要：

We have measured the electron beta decay spectrum of S-35 with an iron-free magnetic spectra In particular, we have searched for the 17-keV neutrino claimed by various authors to exist at the 0.8-1.1 % level. We have successfully fit our data over a large portion of the spectrum (40-166 keV) and find no evidence for the 17-keV neutrino. The branch is determined to be (0.01 +/- 0.15)%, which is in serious disagreement (5sigma) with the (0.84 +/- 0.06)% branch claimed by Hime and Jelley.
