Abstract

CI calculations are performed for the lowest satellite states in the valence and core photoelectron spectra of Ne and Ar, at various excitation levels, up to 4h-3p/4h-4p. Use of relaxed orbitals relative to the doubly ionized system gives significant improvement at the lowest excitation level, and is subsequently employed in all calculations.
