摘要：
The photodetachment cross section and photoelectron angular distribution of metal cluster negative ions are studied theoretically within the consistent many-body theory. Using the Hartree-Fock approximation for the delocalized electrons and the jellium model for the ionic core as the initial approximations, the many-electron correlations are taken into account within the Random Phase Approximation with Exchange. Our calculations demonstrate the dominant role of the many-body effects in the formation of cross sections and angular distributions of photoelectrons emitted from sodium clusters and are in good agreement with the existing experimental data. The concrete comparison of the theory and experiment has been performed for the photoionization of Na7-, Na19-, Na57 anions with entirely closed shells of delocalized electrons.
