The Particular Lines in the Solar Neutrino Energy Spectrum

In this paper, much attention is given to lines of minimum and maximum neutrino energies. Tritium chain of the hydrogen cycle in the Sun including reactions of ³He(e^-,ν_e)³H(p,γ)⁴ is considered. At the distance of 1 a.u., the flux of tritium neutrinos is equal to 8.1 × 10⁴ cm^-2·s^-1. It is an order of magnitude higher than the flux of the (hep)-neutrinos. Radial distribution of ³H-neutrinos yield inside the Sun and their energy spectrum which has a form of line at the energy of (2.5 - 3.0) keV are calculated. The flux of thermal tritium neutrinos is accompanied by a very weak flux of antineutrinos (~10³ cm^-2·year^-1) with energy
