Binding Energies and Spectra

• The UK ESCA Users Group Database of Auger parameters 
  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. Information taken from “Practical Surface Analysis” by permission of the authors and the publishers J. Wiley and Sons.
• Empirically Derived Atomic Sensitivity Factors for XPS 
  This database contains the empirically derived atomic sensitivity factors relative to F 1s for most of the elements. Values are given for the primary and some secondary peaks. Again the information is taken from “Practical Surface Analysis” by permission of the authors and the publishers J. Wiley and Sons.
• LaSurface AES/XPS database of energies and spectra.
