FWHM for Peak-fits

Monochromatic XPS using Pass Energy = 50 eV (this PE give Ag (3d5) FWHM = 0.75 eV)
or PE = 25 eV (that gives Ag (3d5) FWHM = 0.64 eV)

All values were obtained by peak-fitting pure chemical compounds, natural crystals, or man-made single crystal cleaved in air to expose fresh bulk.

All FWHM values were obtained from monochromatic XPS spectra contained in the XPS Spectra-Base of >70,000 available on this website.

All pure metal oxide FWHM data were collected by using the Ni metal Charge-control Mesh-screen

FWHM from Pure Metals / Elements

and a few compounds
