【 摘 要 】

We discuss the effect of breakup on the complete and total fusion cross sections of weakly bound nuclei, both stable and radioactive, at near barrier energies. We show that there is suppression of the complete fusion of non-halo nuclei and total fusion of neutron- halo nuclei at energies above the barrier, whereas there is some enhancement at sub-barrier energies. We investigate a systematic behaviourfor this effect for several weakly bound systems.
