Effects of coupling to breakup in the 6, 7Li+64Zn systems at near-barrier energies
Elastic scattering angular distributions for the weakly bound nucleus Li-7 on Zn-64 have been measured in a wide angular range at energies around the Coulomb barrier. The present experimental data and our previously measured elastic scattering data for the system Li-6 + Zn-64 have been analyzed within the continuum-discretized coupled-channels method, where the resonant and nonresonant states of the projectile are taken into account. In this theoretical framework, we have also analyzed our previously measured excitation functions of elastic scattering at backward angles and the corresponding barrier distributions for the same systems. A good agreement between the experimental data and the calculations has been observed. The obtained results, besides confirming the importance of the coupling to the breakup channels in collisions with weakly bound nuclei, show that, in the case of Li-6, the inclusion of the resonant states of the projectile produces non-negligible effects.
