Many-body perturbation theory (MBPT) calculations of the photoionization cross-section of atomic Sc have been performed from threshold to 70 eV. We consider excitations from the 3p, 3d, and 4s subshells. Over a broad energy range, the resonances, which are split into a number of multiplets, dominate the cross-section. The interaction between the resonances and the channels is significant. Good qualitative agreement with experiment is found.
