Indirect study of (p, alpha) and (n, alpha) reactions induced on boron isotopes

Several experiments were performed to investigate both (p, alpha) and (n, alpha) reactions induced on boron isotopes, by means of Quasi-Free (QF) reactions induced on deuteron target. The experimental study of the astrophysically relevant, (11)B(p, alpha(0))(8)Be reaction was performed by selecting the QF-contribution on the (2)H((11)B, alpha(8)(0)Be)n reaction. Moreover, due to the large interest of a better understanding of (n, alpha) reactions both for nuclear and astrophysical developments, a preliminary study of the (10)B(n, alpha)(7)Li through the QF (2)H((10)B, alpha(7)Li)p reaction was also performed. The results concerning the two experiments will be shown and discussed.
