It is well established that the peripheral nuclear reaction processes such as the elastic and
inelastic scatterings are mostly sensitive to the nucleus-nucleus interaction potential at
large separation distances outside the Coulomb barrier 1. In this region, the attractive
nuclear potential weakens in favor of the repulsive Coulomb potential. On the other
hand, the nuclear fusion and other tunneling related phenomena such as ? and cluster
decays are extremely sensitive to the interaction potential in the partial and full overlap
density regions of the dinuclear system, in addition to the vicinity of the Coulomb
barrier 2, 3, 4. This is the reason why many potentials successfully fit the scattering
data but fail to describe the fusion data if no modifications were introduced, especially
at energies below the Coulomb barrier 5, 6, 7. An example is the semi-microscopic
double-folding potentials based on the bare M3Y nucleon-nucleon (NN) interaction or
its density dependent form. Such potentials well reproduce most of the experimental
data of peripheral reactions 8, but fail to explain many reactions that are strongly
influenced by internal region of the potential 9. Another example is the discrepancy
between the small diffuseness values of the nuclear potential that extracted from fitting
scattering data and its larger values required to reproduce the fusion cross-section data
