PHENOMENOLOGICAL AND SEMI-MICROSCOPIC STUDY OF THE p, d, 3 He and 4 He ELASTIC SCATTERING ON 6 Li

Abstract

The elastic scattering of protons, deuterons, 3 He and 4 He on 6 Li at different incident energies have been analyzed in the framework of the optical model using ECIS88 as well as SPI GENOA codes. The potential parameters were extracted in the phenomenological treatment of measured by us angular distributions and literature data. A good agreement between theoretical and experimental differential cross sections was obtained in whole angular range. Parameters for real part of potential have been also calculated microscopically with single- and double-folding model for the p, d, 3 He and 4 He scattering, respectively, using DFPOT code. For best agreement with experiment the normalization factor N for the potential depth is obtained in the range of 0.7- 0.9. For the 3 He scattering, the elastic triton transfer mechanism has been taken into account by DWBA using DWUCK5 code.
