Abstract
The effect of the breakup channel on the fusion reaction of weakly bound systems by means of a quantum mechanical approach has been discussed. The total fusion reaction cross-section sigma(fus), the fusion barrier distribution D-fus and the mean angular momentum < L > for the systems He-6 + Zn-64, He-6 + Bi-209, B-8 + Ni-58 and Be-11 + U-238 have been calculated. The inclusion of the breakup channel is found to be very essential in the calculations of the fusion reaction for systems involving light halo nuclei especially below the Coulomb barrier V-b. The results of the calculations of sigma(fus), D-fus and < L > agrees quite well with the corresponding experimental data.
