Abstract
In this work, the transfer reactions proceeding in the \(d{-}d\) system, such as \(D(d,p)T\) and \(D(d,n){}^{3}\) He, are studied by means of the microscopic multichannel cluster approach in the oscillator representation. Both reactions are of great interest for pure and applied physics. Their total and partial astrophysical \(S\) factors are calculated at low energies. The contributions of the different channels are discussed, and the most important ones are carefully analyzed. Manifestations of the nuclear tensor force in dynamics of the studied transfer processes are considered. A comparison of the results with experimental data demonstrates a good agreement.
