Analysis of the nuclear potential for heavy-ion systems through large-angle quasi-elastic scattering

A study on the surface diffuseness parameter of the nuclear potential for the reactions of 208Pb with 48Ti, 54Cr, 56Fe, 64Ni, and 70Zn is performed using large-angle quasi-elastic scattering experimental data. Diffuseness parameters that are considerably lower than the standard value of around 0.63...
