The energy dependence of the optical potential for the elastic scattering of {sup 6}He on {sup 209}Bi at near and subbarrier energies is studied. Elastic angular distributions and the reaction cross section were simultaneously fitted by performing some modifications in the ECIS code. A phenomenological optical model potential with the Woods-Saxon form was used. There are signatures that the so-called breakup threshold anomaly (BTA) is present in this system having a halo projectile {sup 6}He, as it had been found earlier for systems involving stable weakly bound nuclei.
