This work suggests a theoretical approach for the description of a primary x‐ray beam by means of the K fluorescence which it excites on a set of thin targets made of pure elements. Physical quantities, defined as weighted integrals over hv of the photon spectral distribution, are obtained directly as weighted integrals of the Kα yields over the variable E z (the ionization energy of the K shell of the element with atomic number Z ), without needing any explicit reconstruction of the spectral distribution. The set of Kα yields produced by an x‐ray beam as a function of E z is a functional description of the exciting beam. Theoretically, such a description is suited to x‐ray fluorescence analysis.
