TL;DR: A neutrino burst was observed in the Kamiokande II detector on 23 February, 7:35:35 UT (7.1 min) during a time interval of 13 sec as mentioned in this paper.

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, the number of electron-like single-prong events is in good agreement with the predictions of a Monte Carlo calculation based on atmospheric neutrino interactions in the KAMIOKANDE detector.

TL;DR: Within experimental errors, the Kamiokande-II value is in agreement with the corresponding value obtained in the /sup 37/Cl radiochemical detector in essentially the same time period.

TL;DR: The nature of the single, observed neutrino burst coincides remarkably well with the elements of the current model of type-II supernovae and neutron-star formation.
