An analysis of cross-sections of 9Be + 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 of 9 Be ions on 28 Si 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.
