Abstract
Many-body effects in photodetachment from negative ions are discussed in this article. A short survey of model and ab initio many-electron approaches applied to the study of negative ions is presented. Manifestations of the dynamic many-electron effects such as the interference between different channels, the polarization interaction, core relaxation and screening of the interelectron interaction in one-photon photodetachment processes are considered. Attention is centred on the resonances in the single-electron photodetachment cross section.
