An application of the equation (1) to the semiquantitative analysis of solid surface by X-ray photoelectron spectroscopy were performed. chemical formula……(1) Where n is the concentration of the element in terms of atoms per unit volume, N is the intensity of ejected photoelectrons, σ is the photoionization cross section, λ is the mean free path for photoelectron in the sample, and S is the spectrometer (sensitivity) factor. The atomic ratios of oxygen to metal element in some oxides could be obtained with satisfactory results by the application of theoretical values of photoionization cross sections and mean free paths. In this case the summation of main and satellite peak intensities were employed for the calculation. Furthermore the atomic ratio of metallic state elements, oxide state ones and oxygen on copper-nickel alloy surface and surface enrichment of nitrogen and sulfur on iron surface were discussed.
