Microscopic approach for calculations of cross sections and optical potentials of nucleus-nucleus interaction at intermediate energies

Nucleus-nucleus scattering is considered in the high-energy approximation and basing on the Glauber-Sitenko microscopic theory in its optical limit. Analytical expressions to the eikonal phases of scattering are given when one uses the realistic Fermi-type potentials and nuclear density distributions. The effect on total reaction cross sections of the trajectory distortion and of the dependence of nucleon-nucleon forces on nuclear density is demonstrated. A sensitivity of total cross sections is studied to the models selected for the projectile nucleus 6He with the neutron halo. The semi-microscopic optical potentials are introduced for description of the elastic differential cross sections. Comparison of calculations with the existing experimental data is made
