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.

A spectrometer for single crystal neutron diffraction

Journal of Scientific Instruments, 1955
A description is given of an instrument for neutron crystallography, specially designed for measurements with single crystals. The small size is in marked contrast with that of the conventional spectrometers designed for powder diffraction methods.

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.

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.

A SINGLE-CRYSTAL NEUTRON-DIFFRACTION INVESTIGATION OF SPODUMENE AT 54 K

The Canadian Mineralogist, 2003
A single-crystal investigation of spodumene from a granitic pegmatite in Minas Gerais, Brazil, was undertaken using neutron (54 K) and X-ray diffraction (room temperature) (R all = 2.8% and 1.9%, respectively). In both refinements, space group C2/c was assigned; the presence of several reflections violating the c glide plane in the low-temperature ...

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.

Single-Crystal Neutron Diffraction Analysis

Nature, 1951
IN the past five years, neutron diffraction analysis has been carried out with wide neutron beams and specimens of several cubic centimetres in volume, in order to obtain a manageable diffracted intensity. Such an expedient has many disadvantages.

Electron Diffraction of Polymer Single Crystals

1991
Single crystals of natural and synthetic polymers may be grown from dilute solutions. These micro single crystals with lateral dimensions of the order of 2 to 10 µm and 50–200 A thick are suitable for an examination by electron microscopy and transmission electron diffraction.

A furnace for X-ray diffraction studies of single crystals

Journal of Physics E: Scientific Instruments, 1973
A miniature furnace suitable for the collection of single crystal x-ray diffraction data at temperatures between room temperature and about 200°C is described. The device was primarily designed for solid-state phase transformation investigations, but may be used for general diffraction studies. Commercially available goniometer heads require only minor

Single-Crystal X-Ray Diffraction

1986
Abstract The primary goal of single-crystal x-ray diffraction is to determine crystal structure and the arrangement of atoms in a unit cell. This article discusses the diffraction of light through line gratings and explains the significance of crystal symmetry, space groups, and diffraction intensities.
