    Notes: A simple equation relating the intensity of characteristic X-ray lines to their respective weight fractions has been obtained for a thick sample excited by an isotopic source. It follows from the equation that a single intense line in a standard sample suffices to generate calibration constants over a wide range of elements. Validity of this aproach has been demonstrated by the analysis of a standard soil sample using only the Fe Kα line for calibration. A procedure for correction of peak overlaps has been given using the Kβ/Kα ratios, modified by the matrix effects. The method is very useful for the analysis of soil samples and can be conveniently applied to other matrices.

    Theoretical evaluation of overlap coefficients in XRF spectra (1981)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: An attempt has been made to obtain theoretically the overlap coefficients of interfering lines in XRF spectra. The peaks have been analytically represented by a Gaussian function and the overlap evaluated for Covell integration. The coefficients for a wide range of elements and for various detector resolutions have been computed as a function of integration window width. The variation with window width of evaluated coefficients is compared with published experimental values.
