Abstract

A study on neutrino magnetic movement was presented using solar neutrino data obtained from Super Kamiokandel (SK). The distortions to the energy spectrum of recoil electrons from magnetic scattering by nonzero neutrino magnetic movement were also studied. The systematic uncertainty of the reconstructed energy of electrons between 5 and 20 MeV was found to be less than 0.64%. The limits on the neutrino magnetic moment were also obtained by analyzing the SK day-night energy spectra.
