Résumé : The 2H(d,p)3H, 2H(d,n)3He, and 2H(d,γ)4He reactions at low energies are studied with realistic nucleon-nucleon interactions in an ab initio approach. The obtained astrophysical S-factors are all in very good agreement with experiment. The most important channels for both transfer and radiative capture are all found to dominate thanks to the tensor force. © 2012 American Institute of Physics.
