The astrophysically relevant (7)Li+p ->alpha+alpha reaction was investigated via the THM by selecting the quasi-free contribution to the measured (3)He+(7)Li ->alpha+alpha+d three-body process. This investigation is mainly aimed at testing the validity of the pole approximation in the THM against the bound structure of the Trojan-horse nucleus. The three-body experiment was performed at 33 MeV, corresponding to a (7)Li-p relative energy ranging from 0.2 to 7 MeV. The quasi-free (7)Li+p cross-section was compared with the free reaction cross-section as well as with indirect data from a previous THM experiment. The good agreement between data sets throughout the energy range investigated provided a very important validity test of the pole approximation for the THM.

Abstract
The astrophysically relevant (7)Li+p ->alpha+alpha reaction was investigated via the THM by selecting the quasi-free contribution to the measured (3)He+(7)Li ->alpha+alpha+d three-body process. This investigation is mainly aimed at testing the validity of the pole approximation in the THM against the bound structure of the Trojan-horse nucleus. The three-body experiment was performed at 33 MeV, corresponding to a (7)Li-p relative energy ranging from 0.2 to 7 MeV. The quasi-free (7)Li+p cross-section was compared with the free reaction cross-section as well as with indirect data from a previous THM experiment. The good agreement between data sets throughout the energy range investigated provided a very important validity test of the pole approximation for the THM.| File | Dimensione | Formato | |
