摘　　要：Recently,Newton et al.found that the diffuseness parameters extracted from the fusion excitation functions above the barrier energies are obviously greater than the commonly accepted value of 0.63 fm.Recently, Newton et al. found that the diffuseness parameters extracted from the fusion excitation functions above the barrier energies are obviously greater than the commonly accepted value of 0.63 fm. The reason for the large discrepancies in the diffuseness parameter extracted from scattering and fusion analyses remains unknown. Recently, large-angle quasi-elastic scattering has also been used to study this subject. Additionally, Hinde et al. have used the oscillatory quasi-elastic Mott scattering at near-barrier energies to determine the surface diffuseness parameter for a symmetric system.
