Abstract

A 2.1 kton yr exposure of data from the Irvine-Michigan-Brookhaven detector has yielded 72 atmospheric neutrino events with a vertex contained inside the fiducial volume and at least 0.95 GeV of visible Cerenkov energy. The ratio of these two ratios \(muonliketotal\)_Data∧(muonliketotal\)MC was found to be 1.1^+0.07-0.12\(stat\)+/-0.11\(syst\). The zenith angle dependence of this ratio of ratios is consistent with being flat. The region of ²\(2θ\)>0.5 and δm²>9.8×10⁻³ eV² has been excluded to the 90% confidence level for v_μ-->v_e oscillations while the region of ²\(2θ\)>0.7 and δm²>1.5×10⁻² eV² has been excluded to the 90% confidence level for v_μ-->v_τ oscillations.
