Abstract
In this work, the elastic scattering of Li-6+Si-28 system at wide range energies from 76 to 318MeV is analyzed. The analysis is carried out in the framework of the optical model (OM). Two different methods are adopted for nuclear optical potential of this system. The first method is the double folding cluster (DFC) for the real part supplied with an imaginary part in the Woods-Saxon (WS) form. In the second one, the double folding (DF) model based upon Sao Paulo potential (SPP) is used as real and imaginary parts each multiplied by a corresponding normalization factor. For Si-28, the full alpha-cluster density is considered while the alpha-deuteron (alpha-D) structure is considered for Li-6. Therefore, the DFC real central part is calculated by folding both alpha-n and alpha-alpha effective interaction between target and nuclei over the cluster densities of the target and projectile. The derived renormalized potentials give a successful description of the data. The present results are in good agreement with the previous work. This agreement confirms the validity of the present methods to generate nucleus-nucleus optical potentials.
