Few-Body Reactions in Nuclear Astrophysics: application to [sup 6]He and [sup 9]Be production

Abstract

In this work we obtain the astrophysical reaction and production rates for the two‐particle radiative capture processes α+n+n→ 6He+γ and α+α+n→ 9Be+γ. The hyperspherical adiabatic expansion method is used. The four‐body recombination reactions α+α+n+n→ 6He+α, α+n+n+n→ 6He+n, α+α+n+n→ 9Be+n and α+α+α+n→ 9Be+α are also investigated.
