Abstract

In this paper, a simultaneous analysis of the elastic scattering data of the 16o+160 system for the energy range 5-10 MeV/nucleon is performed theoretically within the framework of the optical model formalism, by using the alpha-alpha double folding cluster potential. The a-a double folding cluster potential is evaluated by using the alpha-cluster distribution densities in the usual nucleon-nucleon double folding process with an effective alpha-alpha interaction potential. The results of the a-a double folding cluster potential analysis are compared with the findings of the phenomenological Woods-Saxon squared and nucleon-nucleon double folding potentials. All potentials have exhibited a very good agreement with the experimental measurements for the elastic scattering angular distributions. Furthermore, it is shown that, the a-a double folding cluster potential and nucleon-nucleon double folding potential calculations provide very consistent results with each other. Thus, the O-16+O-16 system has been described by optical potentials having a deep real potential part and a weak absorptive imaginary potential part.
