Comparison of the nucleus-nucleus potential evaluated in the double-folding and energy density approximations and the cross-sections of elastic scattering and fusion of heavy ions
Abstract
The nucleus-nucleus potentials evaluated in the double-folding and energy density approximations with and without the contributions of the kinetic energy of the nucleons are discussed in detail. The nuclear part of nucleus-nucleus potentials obtained in the double-folding approach is close to the one calculated in the energy density approximation without the contributions of the kinetic energy. The cross-sections of fusion around the barrier and elastic scattering are calculated for the systems 16O + 208Pb, 40Ca + 40Ca, 16O + 56Fe, 16O + 92Zr using the total nucleus-nucleus interaction. It is shown that taking into account the contribution of kinetic energy to the potential allows simultaneously describes the experimental cross sections of the fusion and elastic scattering.
