Abstract

Data from the Kamiokande detector were used to study the atmospheric (v_μ + v_μ) (v_e + v_e) ratio in the multi-GeV energy range. The observed ratio of μ-like to e-like events relative to the calculated ratio, (μ/e)_data/(μ/e)_MC = 0.57_-0.07^+0.08 ± 0.07, suggests that the atmospheric (v_μ+v_μ) (v_e+v_e) ratio is smaller than expected for these neutrino energies. Also studied was the zenith-angle dependence of the above ratio. Results of an analysis of neutrino oscillations are presented.
