Radiative 3He(2H,g)5Li capture at low deuterium energy

TL;DR

This paper investigates the low-energy radiative capture of deuterons by helium-3, calculating cross sections and reaction rates using a potential cluster model, and compares results with experimental data and other light cluster reactions.

Contribution

It introduces a potential cluster model with forbidden states based on Young diagrams to accurately reproduce experimental data for the 3He(2H,g)5Li reaction at low energies.

Findings

Reproduced experimental cross sections and S-factors from 200 keV to 1.4 MeV.

Provided a parametrization of the reaction rate.

Compared reaction rates with other light cluster reactions.

Abstract

The results are presented on the total cross sections, astrophysical S-factor, reaction rate of the deuteron radiative capture on 3He at the temperatures from 0.03 up to 3 T9 calculated in the framework of the potential cluster model with the forbidden states coming from the classification of the orbital states by the Young diagrams. Within the used model and exploited Young diagram classification made it possible to reproduce the general features of the available experimental data on the cross section and reconstructed astrophysical S-factor in the energy range from 200 keV up to 1.4 MeV. The parametrization of the obtained reaction rate has been found and been compared with some other actual reactions with light clusters.
