Abstract: (APS)
A magnetic spectrometer at the Bevatron has been used to study the low-neutrino-energy ends of the Kμ3 and Ke3 spectra. The spectra are found to agree well with the V−A predictions for massless neutrinos. The upper limits (90% confidence level) are 650 keV for the muon-neutrino mass and 450 keV for the electron-neutrino mass.
