Abstract：
The interaction potentials between two heavy ions are calculated by using the energy density formalism and the nuclear Fermi density distributions,the factor of the neutron skin and the surface diffusion of the neutron distribution increasing with the increases of the neutron excess is considered.In this calculation,the experimental fusion barriers are well reproduced,and improved for the intermediate heavier nuclear systems.It is found that the neutron skin and the neutron distribution diffusion can explain the influence of the neutron excess degree of freedom on the proximity scaling.
