Analysis of the dependence parametrization of the allocations of heavy ions on light nuclei elastic scattering diffraction maxima from the projectile energy

Diffraction range of available experimental differential cross sections of heavy ions on light nuclei elastic scattering for the interactive nuclei 17 pairs with 4 ≤ A ≤ 20 have been analyzed in the projectile energy wide interval from 1 to 100 MeV/nucleon. Diffraction maxima and minima positions in the transferred momentum coordinates depending on projectile energy demonstrate smooth behavior at energies higher 2 ÷ 4 MeV/nucleon and at energies to 30 ÷ 40 MeV/nucleon – practically does not depend on energy. These energy dependences of maxima (minima) positioni can be parameterized by simple functions. It was found the suitable approximations that describe reasonable the energy dependence of the maxima (minima) positions of the experimental elastic scattering differential cross sections. These approximations were evaluated with the same parameters for all colliding nuclei groups.
