Neutron Diffraction from Single Crystals

2012
When we discussed the variation of observable symmetry according to the nature of the examining probe, Sect. 1.4, we stated that one possible probe is a neutron beam. As an example, when the structure of elemental chromium is examined by X-ray diffraction, it shows a body-centered cubic arrangement, Fig. 11.1a.

Neutron diffraction by magnetic single crystals

Journal of Physics C: Solid State Physics, 1975
The fundamental equations for the dynamical neutron diffraction including magnetic interaction are developed. Using the close analogy to dynamical X-ray diffraction, the expression for the ratio of reflected-to-incident intensity in the symmetrical Bragg case is derived. Explicit results for a Gd crystal are presented.

Microfurnace for single-crystal diffraction measurements

Journal of Applied Crystallography, 1978
A 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, 1960
The 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.

Montmorillonite: Electron Diffraction from Two-Dimensional Single Crystals

Science, 1972
Some selected area electron diffraction patterns of isolated monocrystalline particles of both Wyoming and Camp Berteaux sodium-monfmorillonites fail to show the mirror plane symmetry required for the accepted structure. A triclinic model deserves consideration.

Femtosecond X-ray Diffraction on DIABN single crystals

15th International Conference on Ultrafast Phenomena, 2006
Structure sensitive methods like time-resolved X-ray diffraction and transient absorption in the mid-IR are combined with UV7VIS transient absorption spectroscopy to probe the charge transfer photo-reaction in single crystals of an aminobenzonitrile derivative.

Single-Crystal-Like Diffraction Data from Polycrystalline Materials

Science, 1999
A method for solving structures from powder diffraction data was developed, and its validity was demonstrated on three complex structures. The method uses a textured sample and exploits the high intensity and parallel nature of synchrotron radiation. In principle, crystal structures as complex as those routinely solved by single-crystal methods can be ...

Rectangular-profile diffraction grating from single-crystal silicon

Applied Optics, 1980
Diffraction gratings having well-shaped rectangular profiles were fabricated by chemical etching of single-crystal silicon oriented in the ?110? direction. The grooves were 2.62 microm deep, 5.4 microm wide, and were separated by 10.2 microm. The diffraction behavior was measured near normal incidence using several laser wave-lengths.

Single-Crystal X-ray Diffraction

2016
Single-crystal X-ray diffraction is an extremely powerful technique to characterize small drug molecules in solid form. It is a mature technique that is becoming ever more automated, and it is increasingly viewed as “routine” in both industry and academia.
