Popis:	A study of the ns0np6 1S0 states in the rare gas ions is described. A large cross section for the production of two vacancies in the ns shell in certain ion-atom collisions is used to settle the dispute over the identifications of the ns0np6 states in Auger spectroscopy. The identifications due to McGuire of the 3s03p6 1S0 and 4s04p6 1S0 states in Ar III and Kr III, respectively, are confirmed. Optical spectroscopy is used to obtain accurate values for the energies of these levels. The large cross sections for the production of two ns vacancies in the rare gases in ion-atom collisions are assumed to be the reason that the ns0np6 1S0 levels are found to be strongly populated in the hollow-cathode discharge compared to light sources where electron-impact excitation dominates.
