**NOTES

  • Be careful using NIST BEs to make chemical state assignments.  Study the Histogram Plots of NIST BEs.  Based on my 30+ years of experience using XPS to analyse materials and solve problems, the NIST BEs in the NIST SRD20 Database are useful as a guide, but their reliability is difficult to know.  Check if the original paper gave a Cu 2p3 BE.  What was the the C (1s) BE?  Does it match your C (1s) BE?  Did the instrument use non-monochromatic Mg X-rays that produce serious heat (up to 200 C) and that produce high energy X-rays called Bremsstrahlung (up to 15 kV in energy) that can degrade some materials?  What was the FWHM of the Ag (3d5)?  Does it match your Energy Resolution (PE) settings close enough?
  • For an in-depth review on the reliability of BEs in NIST database and scientific journals that publish XPS BEs, please read:  “XPS in Industry – Problems with binding energies in journals and binding energy databases”, written by B. Vincent Crist (Sr. Editor of TXL), and published in Journal of Electron Spectroscopy and Related Phenomena, vol 231 (2019) 75-87,  (https://doi.org/10.1016/j.elspec.2018.02.005)
