Resumen

A quantitative study of the surface composition of ferric oxide employing photoemission spectra is presented. It was possible to accurately reproduce the expected composition (Fe_2.00±0.05O₃) by modeling the background as a combination of Shirley-type (Shirley–Vegh–Salvi–Castle) and slope backgrounds through the active approach. The line-shape employed to fit apparent peak asymmetries was the double-Lorentzian. It was possible to resolve a previously unreported satellite located at ~729 eV.
