In a tungsten beam-dump experiment performed at Fermilab, 1480 neutrino-induced muonless events were observed. The prompt ..nu../sub e/ flux was determined both by subtraction of residual ..nu../sub ..mu../ and nonprompt ..nu../sub e/ interactions and by use of the difference between the longitudinal energy deposition of electromagnetic and hadronic showers. The ratio of the prompt ..nu../sub e/ flux to the ..nu../sub ..mu../ flux was measured to be 0.95 +- 0.12 +- 0.08 for E/sub ..nu../>20 GeV and was consistent with unity throughout the range of energy and transverse momentum accessible to the experiment.
