Abstract

The effects of retardation in the Coulomb excitation of radioactive nuclei in intermediate energy collisions $(E_{lab} \sim 100 MeV ∕ nucleon)$ are investigated. We show that the excitation cross sections of low-lying states in ${}^{11}{Be}$ , ${}^{38, 40, 42}S$ , and ${}^{44, 46}{Ar}$ 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.
