    Notes: Abstract Ground state and excited states properties of alkali-metal clusters are investigated within the framework of the jellium model from the standpoint of the Hartree-Fock theory. The present study deals with closed-shell systems with up to 138 delocalized electrons. Dipoles excited states are described within the random-phase approximation (RPA) with full exchange contributions. The total jellium energy is calculated to second order of many-body perturbation theory with exchange contributions being taken into account fully. The correction to the self-energy that is due to the screening of the Coulomb interaction is evaluated by summing polarization diagrams to all orders. The model is used to calculate the ionization potentials of one-valence-electron systems (9, 21, 41). Results are discussed and compared with others which are based on the local-density-approximation.
