Auger parameter shifts in the case of the non-local screening mechanism: Applications of the electrostatic model to molecules, solids and adsorbed species†

摘要: A simple electrostatic model is applied to predict and rationalize the auger parameter shifts in molecules, solids adsorbed species. The valid case of non-local screening mechanism, i.e. when core hole due polarization nearest-neighbour ligands (no charge transfer from localized electronic levels atom with hole, as occurs main peak core-ionized heavier 3dn transition metal ions or light lanthanide ions). To good approximation it shown that: (1) Auger shift a function number, distance, polarizability local symmetry first-neighbour atom; (2) dipole–dipole interactions can play key role determining extent extra-atomic relaxation energy hence shift.
