Modeling the fusion process with a modified Woods-Saxon potential in Ar40 -induced fusion reactions

Abstract

The evaporation cross sections in fusion reactions by $^{40}\mathrm{Ar}$ bombarding deformed nuclei were compared to calculations using a modified Woods-Saxon potential model together with the standard statistical model. The results show that the predictions overestimate the experimental yields of these reaction products up to two orders of magnitude as the charge number of compound nuclei (${Z}_{CN}\ensuremath{\ge}85$) increases, and suggest that the fusion process strongly depends on the orientation of the deformed target according to density-constrained time-dependent Hartree-Fock calculations.
