X-ray attenuation coefficient measurements made on single-crystal silicon specimens by participants in the International Union of Crystallography Attenuation Project are presented for energy range 8-60 ke V. Twelve laboratories using eight different experimental configurations have provided data analysis. A comparison is between techniques at those characteristic wavelengths interest to crystallographers. Comparison these with available theoretical cross sections suggests that a model which...
Abstract The X‐ray refractive index of lithium fluoride was measured to an accuracy a few parts in 10 9 over the wavelength range from AgKβ 1 (λ = 0.497058 Å) CuKα 1.54053 Å). From these results scattering factor for forward direction and anomalous dispersion corrections fluorine were calculated. Good agreement obtained with values calculated using Hönl's theory.
Measurements are reported of the mass attenuation coefficient carbon taken by laboratories participating in International Union Crystallography X-ray Attenuation Project. Data resulting from a similar study using silicon were published earlier [Creagh & Hubbell (1987). Acta Cryst. A43, 102-112]. The data self consistent, for most part, to 0.5% energy range 6 60 keV, and accords well with experimental data. These about 3% less than theoretically calculated [Saloman (1986). Coefficients (Total...
Abstract The identification of iron‐gall inks on a number 18th, 19th, and 20th century documents 12th manuscript has been conducted using near‐infrared Raman microspectroscopy. These historic were found to display characteristic bands generally occurring around 1475 cm −1 , between 1310 1350 (variable), 490–640 (combined broad band), 400 . have promise as analytical spectroscopic markers for in situ non‐destructive ink collections good agreement with data collected laboratory‐prepared...
The x-ray mass-attenuation coefficient of copper was measured at 108 energies between 5 and $20\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$ using synchrotron radiation. measurements are accurate to 0.09 4.5 %, with most being better than 0.12%. imaginary component the form factor also determined after subtracting attenuation contribution due scattering. Measurements were made over an extended range experimental parameter space, allowing us correct for several systematic errors present in data....
Outlined are design features of a versatile high-resolution two-axis diffractometer that is being constructed for operation at the Photon Factory as an Australian national facility. The instrument optional use multiple-imaging plates on translating cassette to allow rapid recording almost complete range data covering both high-angle and small-angle scattering regime or alternatively electronic detectors. will be capable in various modes including following: (i) powder diffraction with...
A regional chemical boundary termed the ‘salt line’, in Vestfold Hills of East Antarctica, has been investigated using X-ray diffraction and electron probe analyses surficial salts, conductivity sediments. West salt line, halite thenardite are abundant. These salts derived from dispersal marine aerosols, saturation sediment by seawater during postglacial transgression, glacial salt-saturated fjord bottom subglacial calcium carbonates formed weathering their substrates occur. Chemically...
X-Ray diffraction is reported from mesoporous silicate films grown at the air/water interface. The were studied both as powdered films, and oriented on silicon or mica sheets. At early stages of growth we observe Bragg a highly ordered cubic phase, with long short d-spacing peaks. We have assigned this discontinuous micellar Pm3n phase in which silica partly ordered. Later retain only known hexagonal p6m peaks lost any order d-spacings longer characteristic structure. framework considerably...
