TL;DR: In this paper, the Kamiokande detector was used to observe atmospheric neutrino interactions in an exposure of 4.92 kt yr and the observed ratio of single ring μ-events to e-events (μ e ) data ( μ e ) MC = 0.60 +007 −0.06 ( stat. ) ± 0.05 ( syst. ) suggests that the atmospheric vμ/ve ratio is smaller than expected.

TL;DR: In this paper, a data sample of 1040 days from the Kamiokande II detector, consisting of subsamples of 450 days at electron-energy threshold = 9.3 MeV and 590 days at = 7.5 MeV, yields a clear directional correlation of the solar-neutrino-induced electron events with respect to the Sun and a measurement of the differential electron energy distribution.

TL;DR: In this paper, the Kamiokande II detector was used to measure the solar neutrino-induced electron events with respect to the Sun and a measurement of the differential electron energy distribution.

TL;DR: An analysis of the Mikheyev-Smirnov-Wolfenstein effect using 1040 days of Kamiokande-II data is reported, which provides constraints on neutrino-oscillation parameters.

TL;DR: Searches for possible day-night and semiannual variations of the {sup 8}B solar neutrino flux are reported based on 1040 days of Kamiokande-II data, but within statistical error, no such short-time variations were observed.
