Optical model potentials for 16O + 16O elastic scattering

Abstract

Angular distributions of the elastic scattering differential cross section data for the 16O + 16O nuclear system in the energy range of 75–480 MeV have been analyzed using the double-folding optical potential model. The real part of the interaction potential is derived on the basis of double folding of different models of interaction such as CDM3Y1, CDM3Y6, DDM3Y1, and BDM3Y1. The imaginary part of the potential is taken as the sum of the imaginary volume term expressed in the phenomenological Woods–Saxon squared form and a derivative Woods–Saxon surface term. Renormalization factors Nr for the various concerned interaction models are evaluated. The potential created by the BDM3Y1 model of interaction has the shallowest depth, which reflects the necessity of using higher renormalization factor. The obtained real volume integral and total reaction cross sections are calculated at different energies using the derived potentials. The obtained results are in agreement with the experimental data.
