摘要：

Studying interactions of radioactive ions with neutrons is particularly demanding and has been performed only in a few cases. Some of these interactions are crucial in several astrophysical contexts. In the present work, the case of the Be-7 destruction induced by the (n,alpha) reaction is investigated at the energies typical of the primordial nucleosynthesis by means of the Trojan Horse Method applied to the H-2(Be-7,alpha alpha)p quasi-free reaction. The Be-7(n,alpha)(4) He cross-section has been measured in a single experiment from similar to 2 MeV down to cosmological energies. The corresponding deduced reaction rate has been adopted to evaluate the impact on big bang nucleosynthesis and on the lithium problem.
