The Auger Parameter
The Auger parameter is defined as A.P. = K.E(Auger) -
K.E.(photoelectron) + Photon Excitation Energy = K.E.(Auger) + B.E.(photoemission)
Where K.E.(Auger) and B.E.(photoemission) are normally measured for the
most intense photoemission and sharpest Auger lines available. Its advantage as a probe of
chages in screening energy is that (unlike photoemission or Auger line measurements taken
separately) it is independent of energy referencing problems whilst still being measurable
to a high precision. Hence small shifts in its value can be measured and interpreted.
This database contains the energies of the principal photoemission and
Auger lines and their corresponding Auger parameters for most of the elements. Most
entries include values for the element in many different chemical states. This information
