Abstract

Highly correlated ionic states that can be probed efficiently by resonant Auger spectroscopy via triple excitation above the core threshold are shown. By using 419 eV photons, two valence electron simultaneously with a N 1s core electron into the 1 πg orbital borrowing intensity via initial and/or final state correlation thus reaching a triply excited neutral intermediate state are given. This triply excited intermediate state will predominantly decay via an Auger process to three-holes two-particles ionic state configurations in the broad 2σg-1 inner valence band.
