Résumé :

A four-cluster microscopic model is used to investigate low-energy 6Li + p and 6Li + n reactions, as well as related reactions, of astrophysical interest. The model involves α + 3He, 6Li(1+, 0+) +p and 6Be(0+) + n (or mirror) configurations with 3He, 6Li and 6Be wave functions calculated variationally in a three-cluster description. The sensitivity to the model space of the 3He(α,γ)7Be and 3H(α,γ)7Li cross sections is discussed. The 6Li(p,γ)7Be cross section nicely agrees with experiment but some overestimation is obtained for 6Li(p,α)3He. The 6Li(n,γ)7Li and 6Li(n,α)t reactions are also analyzed within the same model. © 2002 Elsevier Science B.V. All rights reserved.
