A measurement of the electron neutrino to muon neutrino mixing probability has been conducted in a newly designed narrow band neutrino beam at BNL. The detector employed was 225 metric tons of target and absorber material instrumented with proportional wire chambers located 1 km from the neutrino source. The beamline provided muon neutrinos to the detector at a calculated rate of 1.5 x 10/sup 4/ per m/sup 2/ per 10/sup 12/ protons on target with a relative electron neutrino background at the level of 8.3 x 10/sup -3/. Analysis of data from 3 x 10/sup 19/ protons on target taken at two energies, 1.27 GeV and 1.46 GeV, shows that the nu/sub ..mu../ event energy distribution and rate were consistent with that calculated for the beamline but that the nu/sub e/ event rate was higher than expected.
