A new method for the measurement of X-ray diffuse scattering with a combination of an energy-dispersive detector and source of white radiation

A technique for the measurement of diffuse X-ray scattering by a combination of an energy-dispersive detector and a source of white X-rays is described by taking the instrumental resolution into account. A high-power X-ray generator was used to generate white X-rays. The short-range-order (SRO) diffuse scattering from Au₄Mn alloy was measured and the Warren-Cowley SRO parameters of this alloy were determined up to the 50th shell. The results are in good agreement with those obtained by the angle-dispersive technique. Possible application of this method with the use of X-rays from a synchrotron radiation source is presented.
