Abstract
The α elastic scattering from various targets over a wide range of energy (120-400 MeV) has been analyzed in the framework of the double-folding (DF) optical model potential. The real DF optical potentials are generated based upon the M3Y and JLM effective nucleon-nucleon interactions. Density- dependent versions, DDM3Y, DDJLM, are also considered. The imaginary part of the optical potential is expressed either in a phenomenological Woods-Saxon form or microscopically using a normalization of the real DF potential. The angular distributions of the elastic scattering differential cross sections using the derived microscopic real potentials revealed successful description of nine sets of data all over the measured angular range. The extracted reaction cross sections have been also investigated.
