Comparative study demonstrates the impact of surface energy coefficients on fusion and quasi-elastic reactions, suggesting important implications for nuclear physics.
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 \(γ ₀=1.08948~MeV/fm²\) 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.
