✦ Synopsis

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