Abstract

The neutrino oscillations of the recoil electron energy spectrum and zenith angle variations of the solar neutrino flux were presented using precise measurements from 1258 days of neutrino-electron scattering data in Super-Kamiokande. A strong constraint on neutrino mixing and mass difference in a flux-independent way was obtained due to the absence of zenith angle variation and spectrum distortion. It was shown that two allowed regions at large mixing were obtained using the Super-Kamiokande flux measurement.
