Résumé :

The 7Be(p, γ)8B reaction is investigated through a microscopic three-cluster model, using the generator coordinate method. The 7Be nucleus is described by an α +3He structure, projected on the 3 2- and 1 2- states of 7Be. The model is tested by the calculation of M1 transition probabilities in 8Li and 8B and of the 7Li(n, γ)8Li cross section. At zero energy, we find an S-factor S(0) = 0.030 keV·b, slightly larger than the currently accepted value. © 1988.
