N2 - A precise measurement of the beta-ray spectrum of 35S has been carried out using a Si(Li) spectrometer system to look for the signiture of heavy neutrino emission. The results are consistent with no heavy neutrino admixture, and the resulting upper limits for the mixing |UeH|2 ≲0.3% were determined in the mass range 10-50 keV.
