Comparative study for the elastic scattering of the isobar nuclei 6Li and 6He on 64Zn using different nuclear potentials

The available experimental data for the elastic scattering of the isobar nuclei Li-6 and He-6 on 6464Zn have been reanalyzed in the available energy range using the optical model, double folding (DF) (Sao Paulo), and crystal model (CM). Double-folding (DF) and crystal model (CM) have been used to investigate the experimental data as a real part of the optical potential, while the imaginary part was taken in Woods-Saxon (WS) shape. One value of the real part of the optical potential has been applied to the two systems under consideration. The distance of the closest approach of the Li-6 (He-6) + 6464Zn systems has been extracted from the available experimental data using different methods. The extracted potential from the Li-6 and He-6 elastically scattered by 6464Zn data could be used as the basis for the creation of a simple global optical potential for Li-6 and He-6. The extracted normalization factor (N-r) was equal to the unity during the fitting process avoiding its unfortunate value (in the range 0.5-0.7) exists in the literature. It was observed that interaction distances vary slowly with the energy of the projectile and strongly depend on the projectile properties. The halo properties of He-6 have a significant effect on the calculated reaction cross-sections. Different methods have been applied to He-6 and Li-6 elastically scattered by 6464Zn, where fair agreement between them has been observed.
