Abstract

The classical schemes to convert the x-ray intensity into concentration, using the ZAF or the φ(ρ z ) methods, are valid for specimens having homogeneous composition and flat surfaces. Quantitative schemes have also been developed for x-ray microanalysis of multi-layered specimens. More recently, a quantitative method has been proposed for the microanalysis of spherical inclusions embedded in a matrix.

For the case of specimens having a non-planar surface, a quantitative method based on the peak to background ratio, using photons of the same energy, has been proposed. in order to test this correction method, a Monte Carlo program has been developed in order to compute the complete x-ray spectrum, characteristic lines plus bremstrallung, emitted from materials having rough surfaces. Figure [1] shows the geometry of the rough surfaces simulated. The parameters of these surfaces are the summit semi-angle, θ, and the height of the roughness, h.
