Abstract
We discuss the role of channel coupling in the surface properties of an internuclear potential for heavy-ion reactions. To this end, we analyze the experimental quasielastic cross sections for the and systems using the coupled-channels approach by including the vibrational excitations in the target nuclei. While earlier studies have reported a negligible influence of vibrational excitation on the surface diffuseness parameter for spherical systems, we find a significant effect for the C + Pd systems. Our systematic study also reveals influence of transfer couplings on the surface diffuseness parameter.
