Abstract
In the present work, the \(d+d\) radiative capture process is studied. This process is of significant interest for astrophysical applications. The theoretical framework of the study is based on the microscopic cluster approach in the oscillator representation. The total and partial cross sections for the reaction in terms of the astrophysical \(S\) factors are calculated. A good agreement with experimental data is achieved. The tensor force of the nuclear interaction is shown to play a key role in describing the low-energy dependence of the total cross section (astrophysical \(S\) factor).
