The fusion cross sections of 6Li+208 Pb system at energies near the barrier have been measured by means of the evaporation residue method and have been calculated in terms of the coupled-channels model, taking into account single and double phonon octupole excitations of 208Pb and the 3+ rotational state of 6Li. By comparing the experimental results with the theoretical calculations and with the fusion cross section of 16O+208Pb, in which no breakup happens, we conclude that the fusion cross sections of 6Li+208Pb are suppressed at above-barrier energies due to the effects of 6Li breakup, but below the barrier, the effects of breakup are not clear.
