Abstract
High resolution Auger-electron and double-charge-transfer spectroscopi es have been used to investigate the doubly ionized states in CF4. The double-charge-transfer spectra show that both the lowest singlet and triplet states in the CF4 dication have an energy of 38.0+/-0.4 eV. Au ger-electron spectroscopy gives information concerning higher energy s tates in the CF42+ ion. Peaks have been measured in the double ionizat ion energy range 38-80 eV and have been assigned to the population of dication states using theoretically calculated spectra. Recent data fr om CF42+ fragmentation studies (Codling et al., J. Phys. B 24 (1991) 9 51) are discussed and correlated with the present work. The double-cha rge-transfer and Auger-electron spectra have been analyzed in terms of results obtained by two-particle Green's function calculations.
