Double-folding nucleus-nucleus interaction potential based on the self-consistent calculations

The nucleon density profiles of spherical nuclei are calculated within the self-consistent HFB approach based on the non-covariant energy density functional. For the reactions with light nuclei, the nucleus-nucleus interaction potentials are calculated in the double-folding form with these nucleon densities. The characteristics of the Coulomb barriers obtained are in good agreement with those required to describe the sub-barrier complete fusion. The energy density functional used provides a reliable basis to calculate the nucleus-nucleus potential in the reactions of astrophysical interest. A simple parametrization for the nuclear part of the nucleus-nucleus interaction is proposed to estimate the height, position, and curvature of the Coulomb barrier.
