Description of elastic scattering of heavy ions in the Glauber-Sitenko approach

In the framework of the Glauber-Sitenko approach, analytic expressions are derived for the amplitudes of elastic nucleus-nucleus scattering corresponding to different regimes of collision. An extended optical potential of the Woods-Saxon type is employed in calculations, and the deviation of trajectories by a strong Coulomb field is taken into account. Comparison of the analytic evaluations of cross sections with the numerical results and experimental data show that the approach can be used in the energy region from 10 to 100 MeV/nucleon. In this way, at a given potential, one can find angular ranges where a definite picture of scattering like, for instance, the classical or rainbow scattering, the Fraunhofer or Fresnel diffraction takes place
