A clear physical interpretation of barrier distribution peaks and depressions is proposed. It is based on distance dependent vibration excitation energies near the barrier. Microscopic coupled channel equations with neutron rearrangement coupling were proposed and solved. They used distance dependent Q-values near the barrier. The satisfactory agreement between experimental data and calculation results is obtained for fusion cross sections in two reactions 18O+58Ni, 16O+60Ni in the vicinity of the Coulomb barrier.
