NEUTRINO OSCILLATIONS AND MOMENTS OF ELECTRON-SPECTRA

We show that the effects of neutrino oscillations on B-8 solar neutrin os are described well by the first two moments (the average and the va riance) of the energy distribution of scattered or recoil electrons. F or the SuperKamiokande and the Sudbury Neutrino Observatory experiment s, the differences between the moments calculated with oscillations an d the standard, no-oscillation moments are greater than three standard deviations for a significant fraction of the neutrino mass-mixing (De lta m(2),sin(2)2 theta) parameter space.
