We analyze fusion cross sections induced by the {sup 6}He halo projectile in the framework of the double-folding Sao Paulo potential, which has already been shown to be a reliable potential for the analysis of fusion cross sections induced by stable weakly bound nuclei. The results show that the fusion cross sections of {sup 6}He+{sup 209}Bi, {sup 238}U, {sup 64}Zn are suppressed at energies above the barrier when compared with coupled-channels calculations that do not take into account the projectile breakup, whereas they are in agreement with the calculations at subbarrier energies. The results for the {sup 6}He+{sup 209}Bi system are contradictory to those reported previously.
