Study of the H-3(H-1, gamma)He-4 Reaction in the Energy Range 12-34 keV

The study of the H-3(H-1, gamma)He-4 reaction is of relevance for both nuclear physics and nuclear astrophysics. In nuclear astrophysics, more accurate data should be obtained on the rate of primordial nucleosynthesis reactions that lead to the production of He-4. In nuclear physics, there are theoretical models in which the behavior of the cross section and the S-factor of this reaction in the energy range of the order of tens of keV are in poor agreement with experiment. Thereby, more accurate experimental study of S-factor behavior should be performed in the astrophysical energy range. The experimentally obtained values of the yields for various energies of H-1(+) ions were used to describe the behavior of the H-3(H-1, gamma)He-4 reaction S-factor depending on the energy. As a result, the accuracy of determination of the S-factor of the H-3(H-1, gamma)He-4 reaction has been improved several times.
