Sub- and above barrier fusion of loosely bound ${}^6$Li with ${}^{28}$Si

Abstract

Fusion excitation functions are measured for the system ${}^6$Li+${}^{28}$Si using the characteristic $\gamma$-ray method, encompassing both the sub-barrier and above barrier regions, viz., $E_{lab}$= 7-24 MeV. Two separate experiments were performed, one for the above barrier region ($E_{lab}$= 11-24 MeV) and another for the below barrier region ($E_{lab}$= 7-10 MeV). The results were compared with our previously measured fusion cross section for the ${}^7$Li+${}^{28}$Si system. We observed enhancement of fusion cross section at sub-barrier regions for both ${}^6$Li and ${}^7$Li, but yield was substantially larger for ${}^6$Li. However, for well above barrier regions, similar type of suppression was identified for both the systems.
