  Fusion reactions of neutron-halo nuclei are investigated theoretically with a
three-body model. The time-dependent wave-packet method is used to solve the
three-body Schrodinger equation. The halo neutron behaves as a spectator during
the Coulomb dissociation process of the projectile. The fusion cross sections
of 11Be-209Bi and 6He-238U are calculated and are compared with measurements.
Our calculation indicates that the fusion cross section is slightly hindered by
the presence of weakly bound neutrons.
