Abstract

To investigate the role of surface energy coefficients, we perform a comparative study of heavy-ion fusion and quasi-elastic scattering reactions simultaneously. The results show that the surface energy coefficient significantly influences both fusion and quasi-elastic reactions. Our findings reveal that proximity potential based on the 1977 version, with parameters \ (₀=1. 08948~ MeV/ fm^2\) and \ (k_ s=1. 9830\), successfully reproduces the experimental measurements of fusion and quasi-elastic scattering. The average relative errors for the fusion cross section and quasi-elastic scattering data for selected reactions are 0. 0558 and 0. 0826, respectively.
