This update and revision of the "Fundamental XPS Data to Assist Peak-Fitting"  table was carried out because we found small, but significant errors in BEs and FWHMs which are now correct. 
We added several BEs and FWHM that were missing.

Changes and improvements include:
A.   Correction of several metal oxide metal signal BEs
B.   Correction of BEs of numerous O 1s peak BEs
C.   Coloration of chart to enhance readability and reveal related elements.
D.   Highlighting of FWHM in blue lettering because these are the key to improved peak-fits.
E.   Addition of alkali oxides replacing alkali halides to match presence of other oxides.
F.   Marking of ionic oxides (red dot) that are expected to have C 1s BEs higher than 285.5 eV.
G.   Addition of BEs and FWHMs for Sr, La, Ce, Ne, Os, U, Na, K, Rb, Cs and Th.
H.   C 1s BE from hydrocarbons recovered after ion etching and 10+ hr exposure to UHV.
I.     Addition of radioactivity labels (bottom right corner of each box if radioactive)
J.   Calibration and Std Dev info shown in image below signature

All oxides were analyzed with the SSI patented charge control mesh-screen (grounded, 85% transmis.) sitting 0.5 to 1.0 mm above the sample. The use of the mesh-screen provides optimum FWHM and a very uniform electric field under the screen thereby maximizing BE reliability.  The mesh-screen regulated the current level of the incoming flood gun electrons, thereby minimizing any electron induced degradation. All oxide BEs and FWHMs now match the "Handbook of Monochromatic XPS Spectra of Binary Oxides" (vol 2) and its PDF version. All BEs are referenced to the latest version of reference energies recommended in 1990 by Martin Seah at NPL. The ISO version of reference energies are only 0.05 eV smaller:  (Cu 2p3  932.62 eV in 2001, versus, 932.67 eV in 1990).
