The Study of Fusion and Quasi-elastic Reactions Simultaneously

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 \(\gamma _{0}=1.08948~\mathrm {MeV}/\mathrm {fm}^{2}\) and \(k_\mathrm {s}=1.9830\), 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.
