  Complete fusion excitation functions of reactions involving breakup are
studied by using the empirical coupled-channel (ECC) model with breakup effects
considered. An exponential function with two parameters is adopted to describe
the prompt-breakup probability in the ECC model. These two parameters are fixed
by fitting the measured prompt-breakup probability or the complete fusion cross
sections. The suppression of complete fusion at energies above the Coulomb
barrier is studied by comparing the data with the predictions from the ECC
model without the breakup channel considered. The results show that the
suppression of complete fusion are roughly independent of the target for the
reactions involving the same projectile.
