A Systematic Investigation of Light Heavy-Ion Reactions

Abstract

We introduce a novel coupling potential for the scattering of deformed light heavy-ion reactions. This new approach is based on replacing the usual first-derivative coupling potential by a new, second derivative coupling potential in the coupled-channels formalism. The new approach has been successfully applied to the study of the ${}^{12}$C+${}^{12}$C, ${}^{12}$C+${}^{24}$Mg, ${}^{16}$O+${}^{28}$Si and ${}^{16}$O+${}^{24}$Mg systems and made major improvements over all the previous coupled-channels calculations for these systems. This paper also shows the limitations of the standard coupled-channels theory and presents a global solution to the problems faced in the previous theoretical accounts of these reactions.
