A search was made with the High Resolution Spectrometer at PEP for events with an isolated pair of charged tracks e/sup + -/X/sup - +/ where X is a muon or meson. Such pairs are a possible signature for the decay of massive neutrinos. Only one event was found, for a integrated luminosity of 300 pb/sup -1/, satisfying certain selection criteria and with a mass m/sub ex/ > 1.8 GeV. This result places strong constraints on the existence of new neutrinos with masses from 1.8 to 6.7 GeV and with mixing parameters to the known neutrinos in the range 10/sup -6/ < absolute value of U/sup 2/ < 1. 12 refs., 6 figs.
