Accurate fluorescent intensities of a number of binary and ternary alloys have been calculated by relying on the classical expressions of primary and secondary fluorescence and assuming standard spectral intensity distributions for the primary radiation. It could then be shown that under polychromatic excitation the enhancement effect on the one hand, and on the other hand, the absorption effect with the complications (drift of equivalent wavelength) related to polychromatic radiation, became very much alike on practical terms, apart from generally opposed signs. Both effects could then be dealt with in a homogeneous way and a simple method was derived using ( K − 1) coefficients ‐ see definition in the text ‐ which are fixed from a careful study of binary compositions. Moreover, making provision for fluorescence ‘crossed effects’, the principle of a general and accurate procedure was then established to the end of computerized non‐destructive analysis. The name of ‘generalized iteration method’ is proposed for this procedure.
