The elastic scattering of 6Li and 6He by 208Pb at energies in the vicinity of the Coulomb barrier is studied by means of continuum-discretized coupled-channels calculations. It is shown that the strong reduction of the 6He+208Pb elastic scattering cross section at forward angles is caused by long-range dipole Coulomb excitation of the projectile. The role of breakup in the fusion of halo nuclei is also discussed.
