The effects of retardation in the Coulomb excitation of radioactive nuclei in intermediate energy collisions (Elab∼100  MeV∕nucleon) are investigated. We show that the excitation cross sections of low-lying states in 11Be , 38,40,42S , and 44,46Ar projectiles incident on gold and lead targets are modified by as much as 20% due to these effects. The angular distributions of decaying γ rays are also appreciably modified.
