The effect of {sup 7}Li breakup on the fusion of the {sup 7}Li+{sup 165}Ho system has been investigated using the continuum-discretized coupled channels (CDCC) calculations. Coupling of the breakup channel leads to a large enhancement in the total fusion cross sections at energies below the Coulomb barrier, while it leads to a small reduction of the fusion cross sections at above barrier energies. A large contribution to this enhancement is found because of dipole couplings arising from the L=0 continuum excitation of {sup 7}Li to its ground state. The dynamic polarization potential generated by the {sup 7}Li breakup couplings is found to have an attractive real part at below barrier energies, due to the dominance of dipole (E1) couplings. Inelastic couplings due to the target deformation are found to have negligible effects on the fusion cross section.
