Abstract
The method to find the correction terms for the anomalous scattering is briefly surveyed in the angle-dispersive and the energy-dispersive methods on the powder sample. On the former, a special attention is payed to an influence of the multiplicity on the correction. On the latter, the anomalous scattering terms change from line to line as the X-ray energy of the Bragg peak changes. As a condition to determine the correction term and the temperature factors simultaneously, minimization of an average of Δ ρ (r) 2 in the unit cell is discussed.
