“…Equation (1) was confirmed by multiple-diffraction line-profile measurement using a setup similar to the one reported by Renninger (1937). Dynamical calculations, based on yon Laue's (1931) treatment together with the consideration of the number of effective modes of wave propagation by Chang (1979) gives further support on theoretical grounds.…”

“…where S~ is the sign obtained from the intensity profiles for both Aufhellung (Wagner, 1920; also quoted by Moon & Shull, 1964) and Umweganregung (Renninger, 1937) multiple diffractions ( Table 1). The sign, S R, concerning the rotation of the crystal lattice relative to the Ewald sphere in multiple-diffraction experiments, is determined in the following way:…”

The experimental method for the direct determination of phases, proposed by Chang [Appl. Phys. (1981), A26, 221-226; Phys. Rev. Lett. (1982), 48, 163-166], utilizing the coherent interaction of diffracted X-ray beams according to the dynamical theory in a threebeam multiple Bragg reflection, is applied to the crystal structure of diamond by using an irregularly shaped crystal on a conventional four-circle single-crystal diffractometer. The phases of three reflections can be derived from the signs of three triplet-phase products which are obtained experimentally from three multiplereflection line profiles. Using these phases as a starting set for the direct method, the phases of other reflections are obtained. The computing time for the MULTAN program is therefore drastically reduced.

“…3 It is known that so called "Umweganregung" can give rise to additional intensity near the forbidden Si(200) peak. 4 Nevertheless, our detailed XRD measurements showed that the observed strong intensity of the Gd 2 O 3 (400) peak cannot be caused by Umweganregung only.…”

“…Since I = 0 for this case, the observed pattern is not disturbed by the fluctuation of the base line; this is therefore a good example to show to what degree the calculation can reproduce the detail of the observed pattern. Since Nh=0 in (1), only the last term, Umweganregung (Renninger, 1937), contributes to the intensity. A combination of a strong fundamental point and a strong superlattice one gives rise to a large peak.…”

568La2Pd205 AND La4PdO 7 stable cation arrangements to be produced in both cases. Tables 2 and 5 show that there are few cation-cation distances comparable to the d (M-M) values used in the restrained refinements of the starting models. Although 0 2-has a greater ionic radius than La 3÷ or Pd 2+, the minimum O-O distance in these materials is less than the smallest cation-cation distance, reflecting the greater polarizability of the anion. Thus, it is more useful to consider cation-cation distances than anion-anion contacts in attempting to model such structures. AbstractThe intensity equation of the n-beam interaction based on the kinematical theory lSoejima, Okazaki & Matsumoto (1985). Acta Cryst. A41, 128-133] is examined for the case of X-ray diffraction in KMnF 3. With
