Abstract ： The angular distributions of elastic scattering for the 6 Li +208 Pb system have been measured at several energies around the Coulomb barrier. The parameters of optical potential are extracted by means of a phenomenological optical model analysis. It is found that the real and imaginal potentials show a pronounced energy dependence. The behaviour of the potential at the nearly especially sub-barrier energies in the 6 Li+208 Pb system is quite different from the results of some previous reports observed in other systems, such as 19 F+208 Pb and 16 O+208 Pb. This unusual threshold phenomenon indicates that breakup channel is strongly coupled with the elastic channel and has obvious effects on optical potential.
