Studies on the Chemical Shifts of Auger Electron Energies for Magnesium and Zinc in Their Compounds

Abstract

Abstract The energy shifts of X-ray excited Auger electrons and photoelectrons for zinc and magnesium in their metals, oxides, halides, and chelate compounds are analyzed in terms of the relaxation effect. Zn 2p3⁄2, 3d photoelectron, Zn L3M45M451G Auger electron, Mg 1s, 2p photoelectron and Mg KL23L231D Auger electron peaks were provided for the investigation. The quantitative estimation of the extra-atomic relaxation energies for core electron emission was performed by combining atomic spectral data, XPS and AES data of the compounds. For zinc compounds, extra-atomic relaxation energies increase in the order of ZnF2<ZnCl2<ZnBr2≈ZnO<ZnI2≈ZnS<Zn(acac)2, whilst the values are not fairly systematic for magnesium compounds. The nearest neighbored atom is found to be the important function for the extra-atomic relaxation energies.
