Parametrization of woods-saxon potential for heavy-ion systems

Several elastic scattering angular distributions of ¹²C from target nuclei of A ≥ 39 are analyzed to extract theWoods-Saxon potential parameters with the fixed imaginary potential and Coulomb radius parameters. Using the best fitted diffuseness parameters, the correlations of the real part parameters with A₁ ^1/3 + A₂ ^1/3 and incident energy are revealed, and the systematic Woods-Saxon potential parameters are presented for nucleus-nucleus interaction. The proposed potential parameters can reproduce not only the elastic scattering angular distributions induced by ¹²C, but also many elastic scattering angular distributions induced by the projectiles other than ¹²C, thus providing important inputs for the study of nuclear reactions of heavy-ion systems.
