Abstract

Ejected electrons from the doublet and quartet states of doubly excited N4+(1s3l3l′) ions, produced by 60 keV N6+(1s) + H2, O2 collisions have been measured with high resolution zero-degree electron spectroscopy. Only the doublet states were observed in collisions with H2 gas. Both doublet and quartet states were observed when O2 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.
