The Dependence of Surface Diffuseness Parameter on N/Z Ratio of The Fusion of Neutron-Rich Colliding Nuclei
Surface diffuseness parameter used in Woods-Saxon form of potential have been extracted from a large number of experimentally studied neutron-rich fusion cross sections at near barrier energies. The results of our systematic study reveals that the extracted diffuseness parameter depend linearly on the N/Z ratio of the fusing nuclei. Further, we demonstrated that the extracted values of surface diffuseness parameter lies within the range a = 0.40 to 0.73 fm as compared to commonly accepted value form elastic scattering data i.e. 0.63 fm.
