Systematic study of the fusion barriers using different versions of surface energy coefficients

The study of heavy-ion collisions at low energies (i.e. E < 10 MeV/nucleon) has been attracting a lot of attention since last few decades. This interest is due to synthesis of super-heavy elements in cold fusion reactions. The total interaction potential between the colliding nuclei is the sum of the long range Coulomb repulsion and short range nuclear attraction. In present study, it would be interesting to use different forms of surface energy coefficient γ (taken from different proximity potentials) in the original proximity potential (i.e. Prox 77) and to see which value of γ will yield the fusion barriers closer to the experimental data, while keeping the effective sharp radius Ri constant.
