Anti-Stokes scattering of neutrinos by electrons in a magnetic field

Anti-Stokes scattering of low energy neutrino on relativistic electrons in magnetic field is considered. Scattering cross-section, polarization and mean longitudinal momentum of recoil electrons afler the scattering are calculated as functions of the initial polarization and structural constants of the elecroweak interaction. Possilibility of experimental tests of theories of the electro weak interaction is pointed out.
