    Relationship between counting modes, absolute noise term and the errors of structure functions in the interpretation of small-angle X-ray scattering data (1985)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 18 (1985), S. 55-60

    Notes: The requirements imposed on the magnitude of the noise in a scattering curve in order to minimize the corresponding error in the structure functions are estimated for a given value of the time T in which the scattering curve is recorded. Typical small-angle X-ray scattering (SAXS) curves have been used to check how these conditions are fulfilled when different counting modes are applied for the measurement. It is shown that fixed-time counting is the most practical technique and produces error bands in the structure functions with magnitudes close to the smallest values attainable in SAXS investigations.

    Notes: Following the procedure suggested by May, Ibel & Haas [J. Appl. Cryst. (1982), 15, 15–19] for the correlation of transmission data with the level of neutrons scattered incoherently into the full solid angle 4π measurements have been made of the transmission and incoherent scattering intensities of aqueous buffers of different H2O/D2O ratios at temperatures between 280 and 343 K. That it is possible to extend the proposed calibration procedure to absorbing-ions-containing buffers is also shown.

    The inverse contrast variation in small-angle neutron scattering: a sensitive technique for the evaluation of lipid phase diagrams (1985)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 18 (1985), S. 65-70 
    Details

    Notes: Small-angle neutron scattering experiments have been performed with aqueous dispersions of binary lipid mixtures. One component was protonated, the other was partly deuterated. By varying the mole fraction of the deuterated species the mean scattering-length density of the lipid lamellas and hence the contrast between liposomes and the solvent was changed. It is shown that this inverse contrast variation has the advantage of (i) a simpler data analysis, (ii) an increased resolution of homogeneous and heterogenous lipid distributions and (iii) a considerably increased sensitivity for the evaluation of phase diagrams in segregated lipid mixtures. Phase boundaries can now be determined to an accuracy of better than 1 mol%.

    Borrmann effect for alignment of a four-circle diffractometer (1985)
    Copenhagen : International Union of Crystallography (IUCr)

    Notes: A very simple method is described to align accurately any full four-circle diffractometer with respect to the incident beam. This method relies on anomalous transmission measurements. It has been found that the centroids of the Ge 220 anomalous transmission intensity distributions measured at the four main positions of the χ circle, that is 0, 90, 180, and 270°, not only provide an accurate determination of the reference angles for ω and φ, but also provide an accurate method to align the χ circle with respect to the direction of the incident beam. This procedure promises to be even more helpful for diffractometers installed at synchrotron radiation laboratories than for in-house installations.

    ABSORB: An absorption correction program for crystals enclosed in capillaries with trapped mother liquor (1985)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 18 (1985), S. 75-79

    ISSN: 1600-5767

    Topics: Geosciences , Physics
    Notes: A computer program to calculate the contributions of crystal, capillary and a simple model of mother liquor to the overall absorption of X-rays has been written. It is based on the Gaussian quadrature method of integration; the crystal is described by the polyhedral faces bounding it, the capillary by its diameter, thickness and orientation with respect to the diffractometer axes and the mother liquor by the crystal faces that trap it between crystal and inner capillary wall. The program is written in Fortran for a VAX 11/780 computer and incorporates tables of mass absorption coefficients for silver, molybdenum and copper radiations for easy calculation of linear absorption coefficients.

    Semiquantitative X-ray diffraction method for phase analysis using additions of a foreign component (1985)
    Copenhagen : International Union of Crystallography (IUCr)
    Applied crystallography online 18 (1985), S. 80-84 
    Details
    ISSN: 1600-5767

    Topics: Geosciences , Physics
    Notes: A method is described for semiquantitative X-ray diffraction phase analysis, which involves the addition to the investigated multicomponent system of known large (about 80–95%) amounts of a crystalline substance originally not contained in the system. This results in a decrease of the diffraction line intensities of the components to be measured to small but detectable values. The weight fraction of a component is related to the added fraction of the doping substance and to the fraction of that component remaining in the doped sample. The method is very simple and yields the weight fractions of the major components in the system with a typical error of a few percent. The weight fractions of the minor components cannot be determined with fair accuracy in this way. The method is appropriate in cases where only a small amount of the investigated system is available. Optimum conditions to attain maximum accuracy of the method are discussed.

    The use of an array processor for the simulation of X-ray topographs (1985)
    Copenhagen : International Union of Crystallography (IUCr)

    Notes: The use of a varying-step algorithm now allows the simulation of traverse topographs and of section topographs taking into account the real width of the incident beam. However, computation time remains a critical factor in practical use. With an array processor it is possible to decrease the computation time significantly. It is shown that pictures of good quality may be obtained in a reasonable time using local facilities. The influence of various parameters on the accuracy of the simulations is discussed. It is demonstrated that local machines can be more useful, in crystallography, than giant computers often difficult to reach through the network of communications.
