Background: At energies above the capture barrier, coupled-channels (CC) calculations with a standard nuclear potential diffuseness (0.65 fm) increasingly overestimate experimental capture cross section as the charge product (Z1Z2) of the colliding nuclei increases. It has been suggested this may be linked to energy dissipation outside the capture barrier. Purpose: We investigate quantitatively the role of energy dissipation in suppressing capture in heavy ion fusion reactions. Method: The...[Show more]
