An article from Ana Ferraria
et al. [1] at the Technical University of Lisbon presents some excellent results and analysis of a variety of silver species. Ag 3d5/2 binding energies and Ag Auger parameters using both the M5N45N45 and M4N45N45 peak maxima are included (see Table 1). Curve-fitting of the Ag 3d5/2 line has also been carried out (Figure 1 and Table 1). Of particular note is the presentation of high quality Ag MNN spectra which show distinct peak-shapes for metallic silver, AgNO3, Ag2O and AgO (Figure 2).
