Studying the Effects of Compound Nucleus Energy on Coefficient of Surface Tension in Fusion Reactions Using Proximity Potential Formalism

Abstract

In this investigation, the energy effects of compound nucleus are studied using formalism of proximity potential on the surface tension coefficient (γ). For this purpose, this coefficient in both main and final versions of proximity formalism, which are: Prox.77 and Prox.2010, is corrected based on systematic studying on 60 of fusion reactions. The correction in γ is caused to improve agreeing fusion cross sections with empirical amounts of them specifically in sub-barrier energies. This correction has significant effect on increasing the theoretical amounts of cross sections in the range of Coulomb sub-barrier energies. The produced results show improvement of agreement on theoretical amounts of Coulomb barrier height with corresponding laboratory data in the various collision systems. In addition, the obtained results show that the MP.2010 potential is able to produce laboratory data more accurate rather than other introduced potentials.
