Radial sensitivity of the elastic scattering around the Coulomb barrier energies for weakly-bound and halo nuclei

摘要

The radial sensitivity of the elastic scattering of the weakly-bound ~6Li and halo ~6He nuclei on medium-mass ~(64)Zn target and heavy target ~(208)Pb is examined around the Coulomb barrier energies. We present that very good agreement between theoretical and experimental results have been obtained with small χ ~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 ~6He+ ~(208)Pb 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.
