Abstract
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-,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.
Highlights
The Standard Solar Models (SSM) which describe in details the processes of the neutrino production are in a good mutual agreement
The flux of tritium neutrinos at a distance of 1 a.u. is 8.1 × 104 cm−2·s−1, and it is an order of magnitude greater than analogous flux of the-neutrinos
Radial distribution of the yield of 3H-neutrinos in relative units is close to the similar distribution of 7Be-neutrinos
Summary
The Standard Solar Models (SSM) which describe in details the processes of the neutrino production are in a good mutual agreement (for instance [1,2]). Reactions of hydrogen cycle covering the yield of neutrinos up to two percent accuracy are of particular interest. It is well-known that these reactions are started from the processes p p 2H e e. GORYACHEV the radius of the Sun are presented below Energy spectrum of these neutrinos which is directly determined by the temperature in the solar interior is calculated. SSM’s characteristics obtained in [1] are used in the calculations
