The role of saturation property of cold nuclear matter is examined in order to describe the steep falloff phenomenon of the measured fusion cross sections at energies far below the Coulomb barrier for 58Ni+54Fe colliding system. For this aim, the double-folding microscopic approach which is modified by modeling the repulsive core effects in the nucleon-nucleon interactions is used to calculate the nuclear interaction potential. Moreover, the theoretical values of the fusion cross section, S factor, and the logarithmic derivative are computed using the coupled-channel technique, including couplings to the low-lying 2+ and 3- states in target and projectile. The results obtained reveal that the corrective effects of cold nuclear matter can be responsible for the description of the fusion hindrance phenomenon in our chosen system.
