Elastic scattering angular distributions of 44 MeV/u 40Ar ions on 60Ni, 120Sn and 208Pb targets have been measured in the forward angle region. Optical model analysis shows that near the grazing angle, the angular distributions are refractive and dominated by the Coulomb rainbow. The potentials have a smaller radius than empirical potential which fit low-energy data: this is consistent with a reduction of the real-ion potential at high energy.
