Boron abundances in stellar atmosphere, as well as beryllium and lithium ones,can be relevant for understanding several astrophysical processes, such as primordial nucleosynthesisand spallation reactions in ISM.

Abstract
Boron abundances in stellar atmosphere, as well as beryllium and lithium ones,can be relevant for understanding several astrophysical processes, such as primordial nucleosynthesisand spallation reactions in ISM. For this reason nuclear processes producingor depleting boron isotopes need to be studied at astrophysical energies. The 10B(p,)7Bereaction is the main responsible for the 10B destruction in stellar interior. In such environmentsthis p-capture process occurs at Gamow energy of 10 keV and it takes placesmainly through a resonant state of the compound 11C nucleus. The 10B(p,)7Be reaction asbeen investigated by means of the Trojan Horse Method (THM) applied to 2H(10B, 7Be)nthree-body process and the results are discussed.| File | Dimensione | Formato | |
