Application of the microscopic multichannel cluster approach in oscillator representation to the 2H(d, γ)4He radiative capture

The ²H(d,γ)⁴He radiative capture reaction is studied within the microscopic multichannel cluster approach in the oscillator representation. The total astrophysical S factor for this reaction is calculated and decomposed into contributions of the partial transitions. The influence of the nuclear tensor force on the energy behaviour of the total S factor is examined, and the flat low-energy dependence of the latter is shown to be governed by this force. A fairly good agreement of the calculated results with the experimental data and with an ab initio calculation is achieved. Recommendations based on the findings of the current study are made for the ²H(d, γ)⁴He total astrophysical S factor.
