摘要：
Excitation functions are measured for complete fusion and transfer reactions of Li-6 and Li-7 with Au-197 at energies around the Coulomb barrier. Coupled channel calculations including the couplings to both target and projectile excited states have been performed and are found to explain the data at energies below the barrier. At above barrier energies the complete fusion cross sections are found to be suppressed compared to the coupled channel calculations for both the systems. A systematic comparison of fusion cross-section for halo nuclei He-6,He-8 and weakly bound stable nuclei Li-6,Li-7 on Au-197 target is also presented. Large neutron transfer cross-sections are observed for Li-6,Li-7 as compared to tightly bound projectiles C-12, O-16.
