Abstract
Experimental data show that the elastic scattering cross sections of the neutron-rich nucleus are greatly reduced by the coupling effects from the breakup channels, while those of the proton-rich nucleus are not. Such difference is found to persist in results of systematic calculations of elastic scattering from at 60 and 170.3 MeV and from at 32 and 86 MeV, and elastic scattering from at 55 and 143 MeV and from at 29 and 66 MeV with the continuum-discretized coupled channel (CDCC) method. The Coulomb and centrifugal barriers experienced by the valence proton in the ground state of , which do not exist for the valence neutron in the ground state of , are found to be the reason for such differences in the angular distributions of elastic scattering cross sections of these two weakly bound nuclei.
