The fusion excitation function for a positive Q-value system at near and deep sub-barrier energies using Skyrme energy density formalism

In this paper, without any adjustment, the nuclear interaction potential is obtained in semiclassical extended Thomas-Fermi approach of the Skyrme energy density formalism, where the potential is expressed as the sum of (i) spin-orbit density independent part (attractive) and (ii) the spin-orbit density dependent potential part (repulsive), following our earlier work for arbitrarily chosen Skyrme force SIV over the center of mass energy range 20 to 30 MeV. The total interaction potential is obtained by adding Coulomb potential directly to the nuclear potential. The characteristics of the said interaction potential are used in Wong's formula to calculate the fusion cross-section as a function of center of mass energies
