摘要：

Ejected electrons from the doubler and quarter states of doubly excited N4+(1s3l3l') ions, produced by 60 keV N6+(1s) + H-2, O-2 collisions have been measured with high resolution zero-degree electron spectroscopy. Only the doublet states were observed in collisions with H-2 gas. Both doublet and quarter states were observed when O-2 was used as the target. Two theoretical methods, perturbation theory or Z-expansion (MZ code) and multi-configurational Hartree-Fock (Cowan code) were used for identification of peaks observed in ejected-electron spectra. Contributions of correlation effects are discussed by comparison with other theoretical energies.
