Solar neutrinos: Radiative corrections in neutrino-electron scattering experiments.

Radiative corrections to the electron recoil-energy spectra and to total cross sections are computed for neutrino-electron scattering by solar neutrinos. Radiative corrections change monotonically the electron recoil spectrum for incident 8 B neutrinos, with the relative probability of observing recoil electrons being reduced by about 4 % at the highest electron energies. For p p and 7 Be neutrinos, the recoil spectra are not aaected signiicantly. Total cross sections for solar neutrino-electron scattering are reduced by about 2 % compared to previously computed values. We also calculate the recoil spectra from 13 N and 15 O neutrinos including radiative corrections.
