From: Strain and ligand effects in Pt-Ni alloys studied by valence-to-core X-ray emission spectroscopy

X-ray emission process associated with the Pt d band including the (a) RIXS, the decay of the intermediate state and the shakeup process (valence excitation) are a concerted process; (b) VTC near Pt L3-edge; and (c) VTC above Pt L3-edge. ωNR and ωAR represent the VTC X-ray emission with excitation near resonance and above resonance, respectively as defined in the text.
