Limits on ..nu../sub ..mu../..--> nu../sub tau/ and ..nu../sub ..mu../..--> nu../sub e/ neutrino oscillations have been determined using a massive fine-grained calorimeter exposed to a narrow-band neutrino beam at Fermilab. We have searched for neutrino-oscillation candidates by selecting events with the quasielastic topology. By having a visible energy which is predominantly in the lepton sector, this type of event has sensitivity to neutrino oscillations and a signature which is indicative of the incident neutrino flavor. From cuts on the event energy allowed by the properties of the incident narrow-band beam, we have determined the following limits at the 90% confidence level for the neutrino-mass-squared difference ..delta..m/sup 2/ at maximum mixing: ..nu../sub ..mu../..--> nu../sub tau/, ..delta..m/sup 2/<10.2 eV/sup 2/; nu-bar/sub ..mu../..-->..nu-bar/sub tau/, ..delta..m/sup 2/<6.5 eV/sup 2/; ..nu../sub ..mu../..--> nu../sub e/, ..delta..m/sup 2/<1.8 eV/sup 2/; and nu-bar/sub ..mu../..-->..nu-bar/sub e/, ..delta..m/sup 2/<3.1 eV/sup 2/. In the limit where ..delta..m/sup 2/ becomes large we have found the mixing angle theta satisfies the following limits at the 90% confidence level: for ..nu../sub ..mu../..--> nu../sub tau/, sin/sup 2/2theta<0.34; for nu-bar/sub ..mu../..-->..nu-bar/sub tau/, sin/sup 2/2theta<0.15; for ..nu../sub ..mu../..--> nu../sub e/, sin/sup 2/2theta<0.015; and for nu-bar/sub ..mu../..-->..nu-bar/sub e/, sin/sup 2/2theta<0.04. .AE
