Systematic study of the Woods-Saxon potential parameters between heavy-ions

Experimental elastic scattering angular distributions of 11B,2C,and 16O+heavy-ions are used to studythe Woods-Saxon potential parameters.Best fitted values of the diffuseness parameters are found for each system,and a linear relationship is expressed between the diffuseness parameters and A1/31+A1/32.The correlation of the po-tential depth and radius parameters with A1/31+A1/32is also revealed within the limitations of the diffuseness parameter formula.Because the incident energies of most of the analyzed reactions are below or around the Coulombbarrier,the energy dispersion relation between the real and imaginary potentials is considered in order to investigatethe ratio between the imaginary and real potential well depths,resulting in an expression of W/V.Within the limitation of the volume integrals calculated with the Sao Paulo potential,parameterized formulas for the depth and radius parameters are obtained.The systematic Woods-Saxon potential parameters derived in the present work can reproduce not only the experimental data of elastic scattering angular distributions induced by 11B,12C,and 16O butalso some elastic scattering induced by other heavy-ions.
