Tritium chain of the hydrogen cycle in the Sun including reactions of 3He(e-,νe)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 lower than 18.6 keV. These antineutrinos are produced during Urca processes 3He3H. The flux of the neutrinos of maximum possible energy (line 19.8 MeV) produced due to the (heep)-reaction (related to the (hep)-process) is estimated.展开更多
