We have searched for the effect of a neutrino of mass 17 keV/[ital c][sup 2] in the beta decay of [sup 35]S with an appartus incorporating a high-resolution solid-state detector and a superconducting solenoid. The experimental mixing probability, sin[sup 2][theta]=[minus]0.0004[plus minus]0.0008(stat) [plus minus]0.0008(syst), is consistent with zero, in disagreement with several previous experiments. Our sensitivity to neutrino mass is verified by measurements with a mixed source of [sup 35]S and [sup 14]C, which artificially produces a distortion in the beta spectrum similar to that expected from the massive neutrino.
