By using this double-folding technique, we present that a superior approximation to the standard analytical rigid spheres one could be achieved. The results illustrating the differences for the extensively studied 16O + 208Pb system are presented. It is observed that the potential for the short-ranges, which one expects to be below or up-to the barrier, the analytical approximations are inferior to the double-folding procedure, especially so for the simplest radius choice. Our results clearly show that the analytical approaches are rather poor and the use of the double-folding technique for the Coulomb potential will lead to a better determination of the nuclear potential for the interaction of two nuclei.
