On the possible presence of neutral antileptons of all generations in the solar neutrino flux
The hypothesis that part of solar electron neutrino flux transforms into antineutrinos of the second and third generations and related antiparticles is considered. Complete electroweak spectra of recoil electrons, including impurity components, are obtained and analyzed for the scattering of beryllium monoenergetic solar neutrinos with energies of 0.862 MeV on an electron target.
