摘要

Data from the Kamiokande detector were used to study the atmospheric (nu(mu) + nu(mu)BAR)/(nu(e) + nu(e)BAR) ratio in the multi-GeV energy range. The observed ratio of mu-like to e-like events relative to the calculated ratio, (mu/e)data/(mu/e)MC = 0.57(+0.08/-0.07) +/- 0.07, suggests that the atmospheric (nu(mu) + nu(mu)BAR)/(nu(e) + nu(e)BAR) 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.
