Description
A systematic system of Coulomb barriers is investigated where nucleus-nucleus interactions are calculated within double-folding formalisms consisting of various nucleon interactions. It is shown that for nuclear reactions involving two light nucleons or a light and a heavy nucleus, even with purely simple attractive nucleons, their calculated Coulomb barriers fit experimental ones(within error margins),similar to ones for effective nucleon-nucleon interactions where double-folding potentials are involved.However, as the masses of both interacting nuclei increase, the simple nucleon-nucleon interaction widely deviates from the experimental values. It follows that the density of the interacting particles has a significant effect on the interacting nucleons of both particles. This effect is not clearly revealed with hard-core nucleon-nucleon effective interactions being considered in the construction of double-folding potentials.
