The Single Crystal Diffraction Patterns of Silicon
European Physical Journal D, 1962A triple-crystal diffractometer is used to study the single crystal diffraction patterns of Si (111), (220), (333) and good agreement with the dynamical theory of X-ray diffraction on perfect single crystals is found. This proves the possibility of using Si single crystals as in X-ray spectroscopy for a double-crystal spectrometer with a high resolving

Diffractive optical elements in single crystal diamond
Optics Letters, 2020We demonstrate the design, fabrication, and experimental characterization of near-field binary phase transmission diffractive optical elements (DOEs) in single crystal diamond. Top-hat and arbitrary pattern DOE beam shapers were numerically optimized using an iterative Fourier transform algorithm (IFTA).

Abstract In this chapter, we consider nuclear Bragg scattering from single crystals and in the next chapter the same type of scattering from poly- crystalline materials. If the sample contains unpaired electrons, as in the elements of the first transition series with incomplete 3d electronic shells, then there is also magnetic scattering.

Electron diffraction by single crystals of carbyne
Polymer Science U.S.S.R., 1975Abstract New evidence is presented on the morphology and crystal structure of carbyne, obtained by electron diffraction and scanning microscopy. Arguments are put forward against interpretation of the diffraction patterns of carbyne by twinning of graphite crystallites.

Microfurnace for single-crystal diffraction measurements
Journal of Applied Crystallography, 1978A new furnace design, based on the air-flow principle, is described. The furnace can operate to 400°C with a stability of ± 0.25°C for long time periods, gives access to about 91% of reciprocal space, and mounts on a standard goniometer head. The power consumption at 200°C is 26 W, at 400°C is 40 W. Higher temperatures are attainable.

Single crystal diffraction pattern of germanium
Czechoslovak Journal of Physics, 1960The diffraction pattern for the (111)-reflection of germanium was measured by means of the three-crystal arrangement and compared with dynamical theory. The results obtained indicate the possibility of using germanium crystals for precise measurements in X-ray spectroscopy.

Neutron diffraction on a UGa3 single crystal
Physica B: Condensed Matter, 1999Abstract The magnetic structure of antiferromagnetic UGa3 (TN≈64 K) has been examined by neutron diffraction measurements on a single crystal. The ordered magnetic moment is 0.74(8)μB per U atom at 5 K. From measurements with an applied magnetic field we suggest that the moments are along the [1 1 1] direction. In the vicinity of 40 K the

The diffraction of thermal neutrons by single crystals
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1951Abstract Experimental measurements of the intensity of neutron reflexion by large single-crystal slices are shown to be in agreement with previously published calculations. It is demonstrated that accurate comparison can be made of the structure factors of planes in a zone by the use of cylindrical or pillar crystals, sufficiently ...
