Abstract：
The effect of breakup on fusion for weakly bound projectiles ⁶Li and ⁹Be incident on ²⁰⁸Pb or ²⁰⁹Bi targets has been discussed by comparing experimental fusion excitation functions to the prediction of stranded theory. It is shown intuitively by this comparison that complete fusion of weakly bound projectile with heavy target is suppressed, whereas breakup has every little effect on the total fusion at energies above the barrier. The result indicates that partial fusion of weakly bound nuclei most likely takes place near the absorption region. By means of our observation, we have put forward a relationship between the cross sections of complete fusion and partial fusion.
