Finally, an extension of the one-channel optical model that allows for simultaneous analysis of fusion and elastic scattering is presented and its applications are considered. As a result the Coulomb barrier heights V B and positions R B have been studied. Comparison of the Coulomb barrier heights second column unit is MeV with the theoretical results V DFM B calculated by the DFM third column using density-dependent NN interaction with Migdal forces and by the proximity potentials for some selected fusion reactions.
Proximity potential The proximity potential is a well-known approach for its simplicity and numerous applications to study a variety of phenomena. Table of Contents Developments in sub-barrier reactions. It plays an important role in Heavy Ion Interactions Around the Coulomb Barrier circumstances in nuclear physics as well as in nuclear astrophysics, such as synthesis of superheavy elements and nucleosynthesis in stars. - Spectroscopic study of sub-barrier quasi-elastic nuclear reactions.
A brief conclusion has been given in section. The authors of  have used the Wong formula as a function of the barrier heights corresponding to the deformation parameters to calculate fusion cross section and they have averaged it by the barrier distribution function D B.
This reaction has been considered in the recent experiments of the Australian group . The following article is Open access Comparative analysis of the Coulomb barrier in heavy-ion collisions by the double-folding method O K Ganiev 1 and A K Nasirov 1,2 Published 9 March 2020• In the case of collision of the intermediate and heavy mass nuclei the fusion cross section is determined not only by the Coulomb barrier but the peculiarities of the potential energy surface of the dinuclear system, which is a function of the mass and charge numbers of its fragments.

This circumstance will be discussed later. The strong competition between the repulsive Coulomb potential and the attractive nuclear interaction at the close distances causes the Coulomb barrier and potential well which determine conditions for the realization of the definite reaction mechanism.
47 045115 The double-folding formalism has been applied to calculate the nucleus-nucleus potential by the use of the effective nucleon-nucleon Migdal potential and the nuclear densities of the interacting nuclei presented as the Gaussian-type functions and polynomials. The deviation of the results calculated by the DFM does not exceed 2. From this point of view the DFM is used very widely.barrier height and curvature based on the double-folding formalism.
The couplings between the various reaction channels available for the collision of two heavy ions become especially important at energies near the top of their mutual Coulomb barrier. The analytical expression for the penetration probability is given by the well-known Hill—Wheeler formula  In this work, we have used equation to calculate the capture cross sections.
The proximity potential used in  AW95 and  Prox77 give deviation more than 4MeV from the experimental values of V B for several fusion reactions.

A crucial step in investigating these interactions is the calculation of interaction potential between nuclei that can help us to evaluate the fusion cross-section of various fusion reactions.

In the case of collision of the intermediate and heavy mass nuclei the fusion cross section is determined not only by the Coulomb barrier but the peculiarities of the potential energy surface of the dinuclear system, which is a function of the mass and charge numbers of its fragments.
