Experimental study to explore the ${}^8\mathrm{Be}$ induced nuclear reaction via the Trojan Horse Method

Abstract

To explore a possible indirect method for ${}^8\mathrm{Be}$ induced astrophysical reactions, the ${}^9\mathrm{Be}=({}^8\mathrm{Be}+n)$ cluster structure was studied via the Trojan Horse Method. It is the first time to study a super short life nucleus ${}^8\mathrm{Be}$ via the Trojan Horse Method, and it is the first time to make a valid test for $l=1$ Trojan-horse nucleus. The ${}^9\mathrm{Be}$ nucleus is assumed to have a (${}^8\mathrm{Be}+n$) cluster structure and used as the Trojan-horse nucleus. The ${}^8\mathrm{Be}$ nucleus acts as a participant, while the neutron is a spectator to the virtual ${}^8\mathrm{Be}+d\to \alpha +{}^6\mathrm{Li}$ reaction via a suitable 3-body reaction ${}^9\mathrm{Be}+d\to \alpha +{}^6\mathrm{Li}+n$. The experimental neutron momentum distribution inside ${}^9\mathrm{Be}$ was reconstructed. The agreement between experimental and theoretical momentum distribution indicates that there should be a (${}^8\mathrm{Be}+n$) cluster structure inside ${}^9\mathrm{Be}$. Therefor the experimental study of ${}^8\mathrm{Be}$ induced reactions, for example the experimental measurement of the ${}^8\mathrm{Be}+\alpha \to {}^{12}\mathrm{C}$ reaction proceeding through the Hoyle state, is possible.
