The 7Be(d, α)5Li(p α) and 7Be(d, p)8Be*(p 7Li) reactions at 5 MeV/u

Abstract

The ${}^7$Be(d, $\alpha ){}^5$Li and ${}^7$Be(d, p)${}^8$Be${}^{*}$(p ${}^7$Li) reactions are studied at 5 MeV/u in the context of the cosmological lithium problem. This work aims to probe the contribution of ${}^7$Be destruction mechanisms, particularly through channels that populate intermediate unbound states of ${}^5$Li and ${}^8$Be. The contribution of ${}^7$Be(d, $\alpha$)${}^5$Li(p $\alpha$) reaction is separated from the ${}^7$Be(d, p)${}^8$Be${}^{*}\left(2\alpha \right)$ reaction. The ${}^7$Be(d, p)${}^8$Be${}^{*}$(p${}_1$ ${}^7$Li${}^{*}$) channel is also identified and is useful for an indirect study of the ${}^7$Be(n, p${}_1){}^7$Li${}^{*}$ reaction.
