Özet

The radial sensitivity of the elastic scattering of the weakly-bound Li-6 and halo He-6 nuclei on medium-mass Zn-64 target and heavy target Pb-208 is examined around the Coulomb barrier energies. We present that very good agreement between theoretical and experimental results have been obtained with small chi(2)/N values. The fusion cross-section and volume integrals of the potentials have been deduced from the theoretical calculations for all studied systems at relevant energies. We have also analyzed the elastic scattering of the He-6 + Pb-208 system at E-lab = 14, 16, 18, 22, 27 MeV in order to investigate whether there is a dispersion relation between the real and imaginary parts of the optical potential.
