Radiative 2H3He Capture at Low Energies

Abstract

Within the framework of the modified potential cluster model with forbidden states which follow from a classification of orbital states of clusters according to Young tableaux, results of a calculation of the total cross section and astrophysical S-factor at energies up to 2.5 MeV are presented. It is shown that the implemented model and methods of classification of cluster states according to the Young tableaux enable, on the whole, a valid description of the available experimental data for the total cross sections and the astrophysical S-factor of the process of ²H³He capture in the energy range from 200 keV to 1.4 MeV.
