Recent advances in the mathematical description of the depth distribution of X-ray generation, , have permitted the quantitative analysis of multilayer structures with a precision approaching nm. A weighted average mass absorption coefficient is proposed for use in analysis with L series radiation when the energy separation of the component lines is less than the spectrometer resolution. This is shown to improve agreement between experimental data and the theoretically calculated X-ray intensities. An example of the application of the method to the analysis of a titanium-boron nitride bilayer is described with special reference to the problem of detection of interfacial diffusion and oxidation phenomena.
