    Fitting of the W 4f photoemission spectrum from metallic tungsten using a CR III lineshape (W 4f forum)

    Fitting of the W 4f photoemission spectrum for the element (research grade), data were provided by Vincent Crist (The use of the spectrum requires acknowledging XPS library website, https://xpslibrary.com/, the data is copyrighted). The main peak was fitted with two correlated Coupled-Resonances type III peak. The total background was modeled with a combination of a Tougaard type background and the interchannel coupling with valence band losses background.
