\(\beta = 3E_{\rm{B}} + E_{\rm{K}}\), where \(E_{\rm{B}}\) and \(E_{\rm{K}}\) are, respectively, the binding energy of a photoelectron peak and the Fermi level referenced (see Fermi level referencing) kinetic energy of an Auger electron peak, each involving the same initial core level of the same element.
Notes:
- The initial-state Auger parameter is useful for evaluating the change in the atomic core potential contribution to changes in binding energy between two environments, provided the Auger transition is between core levels that have similar binding energy shifts.
- This parameter has no relation to the asymmetry parameter, which is also given the symbol \(\beta\).
