Elastic scattering analysis of isobar nuclei A=6 projectiles on 12C using different models of optical potential

In this research, we have extracted a new systematic global description for the fifteen data sets of the Li-6+C-12 elastic scattering angular distribution in the energy range of 5.8-600 MeV, and for the seven data sets of the He-6+C-12 elastic scattering in the energy range of 5.9-493.8 MeV using the simple optical model OM potential with fixed radii parameters. We have reanalyzed the two nuclear systems using a microscopic method within the framework of the double folding Sao Paulo potential (SPP) and the double folding cluster model (renormalized DFC1 and non-renormalized DFC2), prompted by the cluster structure of both (He-6 and Li-6) nuclei. We have adding the dynamic polarization potential (DPP) to DFC2, for well reproducing the experimental data, because the elastic scattering of weakly bound nuclei (He-6 and Li-6) is strongly affected by the coupling to other reaction channels, such as break-up. We have studied the effect of hallo properties of He-6 by comparing the reflexion coefficients derivatives and the reduced cross sections (according to different prescriptions) of the two projectiles. The energy dependence for the reaction cross sections sigma(R), real and imaginary volume integrals of the considered reactions and comparing it to the previously reported ones have been investigated. The dispersion relation between real and imaginary parts of optical potential has been investigated for both studied systems. (C) 2021 Elsevier B.V. All rights reserved.
