Relationship between the Auger parameter and the ground state valence charge of the core-ionized atom: the case of Cu(I) and Cu (II) compounds
We develop a simple semiempirical model that correlates the Auger parameter to the ground state valence charge of the core-ionized atom with closed shell electron configuration. Until now, the Auger parameter was employed to separate initial and final state effects that influence the core electron binding energy. The model is applied to Cu(I) and Cu (II) compounds with the Auger parameter defined as α' = Eb FL (2p3/2) + Ek FL (L3M45M45;1G).
