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 is reproduced from Appendix 5 of "Practical Surface Analysis", Vol. 1., 2nd Edition, by C. D. Wagner, eds. D. Briggs and M.P. Seah, Published by J. Wiley and Sons in 1990, ISBN 0-471-92081-9 by kind permission of the Authors and publishers.
