Two algorithms for the evaluation of even moments of the trigonometric structrure factor are described. The first algorithm is based on conventional structure-factor algebra in the complex notation and is applicable to any space group with multiplicity of general positions not exceeding 24. The...
A general and simple rule for the derivation of which reflections should be used for fixing the origin in any of the 230 space groups is given.
The crystal structure of the new mineral takeuchiite, Me3BO5 (Me = Mg, Mn2+, Mn3+, Fe3+, Ti4+), has been derived by matching experimentally obtained high-resolution transmission electron microscope images with computed ones. The crystals are orthorhombic Pnnm or Pnn2, with a= 27.50 (1), b =...
A general formulation of the theory of the secondary radiation yield by X-ray diffraction in a crystal is given which enables such processes as photoelectric effect, fluorescence and thermal diffuse scattering (TDS) to be described in a unified way. Expressions describing TDS by crystals are...
An analytical method for the description and analysis in real space of X-ray Bragg reflections from extended-face crystals is presented. The method is applied to discuss the stationary-crystal diffracted-beam images in both the symmetric and asymmetric reflection positions, to analyse the and :2...
The method of fitting a learnt and continually revised profile to X-ray diffraction step-scan measurements, previously described for protein crystals and a linear diffractometer, has been modified and extended for a wider range of samples and a four-circle diffractometer. Variation of peak width...
