Energy-dispersive analog of the Zernicke-Prins method for determining the atomic radial distribution function

A modification of the Zernicke-Prins method is proposed for determining the radial distribution of atoms in a solid. The modification consists in measuring the spectra of scattered broadband X-ray radiation instead of the angular distribution of a quasi-monochromatic radiation scattered from the probed sample. It is shown that, according to the proposed approach, it is possible to eliminate the principal difficulty of the traditional Zernicke-Prins method, which is related to a limited region of variation of the argument in the measured angular distribution of scattered radiation.
