An attempt has been made to modify the original version of the Aage Winther 1995 (AW95) potential by adding a positive Gaussian part as VRexp(-br2) to investigate the effect of the repulsive core on the sub-barrier fusion cross sections. In order to achieve this goal, we select and evaluate 6 heavy ion fusion reactions with 392≤Z1 Z2≤784 (including 58Ni+54Fe, 58Ni+58Ni, 64Ni+64Ni, 16O+208Pb, 28Si+64Ni, 28Si+100Mo). The obtained results reveal that the original version of the AW potential supplemented with Gaussian positive part successfully reproduces the experimental fusion excitation data for various considered systems.
