    "abstract": "We extend a recent study that explained the steep falloff in the fusion cross\nsection at energies far below the Coulomb barrier for the symmetric dinuclear\nsystem 64Ni+64Ni to another symmetric system, 58Ni+58Ni, and the asymmetric\nsystem 64Ni+100Mo. In this scheme the very sensitive dependence of the internal\npart of the nuclear potential on the nuclear equation of state determines a\nreduction of the classically allowed region for overlapping configurations and\nconsequently a decrease in the fusion cross sections at bombarding energies far\nbelow the barrier. Within the coupled-channels method, including couplings to\nthe low-lying 2+ and 3- states in both target and projectile as well as mutual\nand two-phonon excitations of these states, we calculate and compare with the\nexperimental fusion cross sections, S-factors, and logarithmic derivatives for\nthe above mentioned systems and find good agreement with the data even at the\nlowest energies. We predict, in particular, a distinct double peaking in the\nS-factor for the far subbarrier fusion of 58Ni+58Ni which should be tested\nexperimentally.",
