    Fitting of the Pb 4f photoemission spectrum from pure Lead using a Doniach-Sunjic lineshape (Pb 4f forum)

    Fitting of the Pb 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 a D&S doublet, and a Gaussian doublet was also used, but the D&S line shape is not capable of modeling the maximum of the peaks or the slope after 140 eV.
