Experimental limits on neutrino oscillations

A search for neutrino oscillations in a wide-band neutrino beam at Fermilab with use of the 15-ft bubble chamber is reported. No evidence is found for neutrino oscillations and upper limits are set on the mixing angles and neutrino mass differences in the transitions ..nu../sub ..mu../..--> nu../sub e/, ..nu../sub ..mu../..--> nu../sub tau/, and ..nu../sub e/arrow-right-dash-bar..nu../sub e/.
