The influence changing of Nuclear Potential on Quasi-Elastic Scattering in 16O+160Gd and 12C+197Au Systems

Abstract

In this research, the effect of changing the potential depth V0 on the Quasi-elastic scattering and barrier distribution calculations have been studied using Wood-Saxon (WS) potential for 16O+160Gd and 12C+197Au systems. The chi square (χ2) is applied to compare the best fitted value of the diffuseness parameter between the theoretical calculations and the experimental data. The diffuseness parameter which used in this work is to be at standard value 0.63. The χ2 was applied to most suitable the better fitted value of the potential depth V0. According to the results, we noticed that some systems achieved a good match between the theoretical calculations and experimental data of Quasi-elastic scattering (dσqel/dσR) and the distribution calculations at the standard value of the potential depth or at a value lower than the standard value and no match was achieved at a value greater than the standard value of the potential depth V0. We conclude that the values of quasi-elastic scattering values increase when the value of potential depth decreases.
