  • The beryllium abundance acts as a key role for understanding the inhomogeneous Big Bang nucleosynthesis. In order to measure the ^9Be（p, α）^6Li bare nucleus cross section and S（E） factor at astrophysical energies, the Trojan Horse Method （THM） can be applied.

Abstract: The beryllium abundance acts as a key role for understanding the inhomogeneous Big Bang nucleosynthesis. In order to measure the ^9Be（p, α）^6Li bare nucleus cross section and S（E） factor at astrophysical energies, the Trojan Horse Method （THM） can be applied. The main feature of the method is that it allows to extract the energy dependence for the astrophysical S（E） factor of bare nuclei at very low energies without any extrapolation, by measuring the cross section of an appropriate three body process. Thus the ^9Be （p,α）^6Li has been studied by means of the THM applied to the ^2H（^9Be,α^6Li）n at INFN-LNS, Catania, Italy. The two body reaction cross section has been studied in the energy range of Ecm=0-1 000 keV. Preliminary results are discussed and a comparison with direct data is made.
