Abstract: The effect of the breakup channel on fusion reactions of weakly bound systems by means of semi-classical and full quantum mechanical approaches has been discussed. The total fusion reaction cross-section σ_fus and the fusion barrier distribution D_fus for the systems ⁴He+⁶⁴Zn, ⁶Li+²⁰⁸Pb and ⁷Li+²⁴Mg have been calculated. The inclusion of the breakup channel enhances the calculations of the fusion cross-section markedly below the Coulomb barrier and hindrance above the Coulomb barrier in comparison to the experimental data. The semi-classical calculations agree reasonably with the full quantum mechanical treatment and they were able to reproduce the experimental data in details for the total fusion reaction cross-section σ_fus and the fusion barrier distribution D_fus.
