Abstract
The elastic scattering of a particle from Y-89, Mo-92, Cd106-116, Sn-112, and Sm-144 nuclei (Z = 39-62) at energies around the Coulomb Barrier (CB) is reanalyzed. The goal is to obtain a regional optical model potential (OMP) for this range of target mass numbers with systematic model parameters. For this purpose, we used the folding model (FM) with two different effective nucleon-nucleon (NN) interactions. These effective NN interactions are the density- and energy-dependent JLM and the DDM3Y1 with finite range exchange term, respectively. The derived potentials are used to reanalyze twenty datasets for the considered systems. The OMPs are constructed first using real folded potentials based on JLM and DDM3Y1 effective NN interactions supplied with the conventional Wood-Saxon (WS) imaginary part. These two OMPs potentials are denoted as JLM-R and DDM3Y1-FR, respectively. In addition, the full complex folded OMP based on the complex JLM effective NN is used and denoted as JLM-RI. The semi-microscopic JLM-R and DDM3Y1-FR potentials reproduced the experimental data over the whole angular range very well compared to microscopic JLM-RI potential.
