Nucleus-nucleus reaction total cross sections calculated for the realistic nuclear matter distributions within the Glauber-Sitenko approach

Basing on the thickness (profile) function, previously obtained for the realistic Fermi-type distribution of nucleons in nuclei, calculations are made of the microscopic eikonal phases of the nucleus-nucleus scattering and the total reaction cross sections. In so doing, the phase is deduced to the one-dimensional integral provided that the Gaussian density distribution for the projectile nucleus and the arbitrary shape of the thickness density for the target nucleus are used. The problems of obtained parameters of the point nucleon density are considered. A possibility to approximate the realistic densities by the surface-matched Gaussian functions and dependence of cross sections on the nucleon-nucleon interaction radius are discussed. The in-medium effects and a role of the trajectory distortion are studied. Conclusions are made on physics of the process, and comparisons with experimental data are made with cross sections calculated by using the developed method where no free parameters are introduced
