The solar neutrino spectrum derived from electron scattering and charged current interactions

Abstract

We provide a method for extracting information on the energy spectrum of solar neutrinos directly from the spectrum of scattered electrons. As an example, we apply it to the published Super-Kamiokande data. When combined with data from SNO on charged current interactions this method allows to derive separately the spectra of nu_e and of nu_mu plus nu_tau.
