Description
The $^4$He + $^2$H system is of great importance for nuclear astrophysics because the radiative capture proceeding in this system is responsible for production of the $^6$Li nuclei during the primordial nucleosynthesis. In this work, the $^4$He + $^2$H radiative capture reaction is considered from the microscopic viewpoint within a developed approach [1, 2] based on clustering aspects of nuclear structure and dynamics and formalism of expansions over the oscillator basis. The cross section of the reaction in terms of the astrophysical $S$ factor is calculated. The low-energy dependence of the total astrophysical $S$ factor serves as a source of information useful for the so-called second “lithium puzzle”. A comparison of the obtained results with experimental data is performed.
