The Trojan Horse Method has been applied to the (2)H((9)Be, (6)Li alpha)n three-body reaction in order to investigate the (9)Be(p,alpha)(6)Li two-body reaction, which is involved in the study of light element abundances (lithium, beryllium and boron). A coincidence measurement was performed in order to identify the presence of the quasi-free mechanism in the three-body reaction, needed for the application of the method. The astrophysical S(E)-factor was extracted and compared to direct data. No information about electron screening effects can be extracted due to the poor resolution of the indirect data.

Abstract

The Trojan Horse Method has been applied to the (2)H((9)Be, (6)Li alpha)n three-body reaction in order to investigate the (9)Be(p,alpha)(6)Li two-body reaction, which is involved in the study of light element abundances (lithium, beryllium and boron). A coincidence measurement was performed in order to identify the presence of the quasi-free mechanism in the three-body reaction, needed for the application of the method. The astrophysical S(E)-factor was extracted and compared to direct data. No information about electron screening effects can be extracted due to the poor resolution of the indirect data.
