An analysis of cross sections of⁹Be +²⁸Si interaction in the framework of the double folding model

Abstract

In this paper the experimental data on the differential cross sections for elastic scattering of9Be ions on28Si nucleus at the energies of the incident nucleus ranging from 12 to 201.6 MeV were analyzed in the framework of the double folding model using the Paris NN-potential CDM3Y. A good agreement with the experimental angular distributions of differential cross sections for elastic scattering was obtained and the values of the total reaction cross sections were calculated. When the double folding potential was used as real and imaginary parts, no manifestation of the threshold anomaly was detected. The reason for such a behavior of the potential can be explained by the presence of break up and/or transfer channels at low energies.
