IT has been shown by Herr Laue and his colleagues that the diffraction patterns which they obtain with X-rays and crystals are naturally explained by assuming the existence of very short electromagnetic waves in the radiations from an X-ray bulb, the wave length of which is of the order 10−9 cm. The spots of the pattern represent interference maxima of waves diffracted by the regularly arranged atoms of the crystal. Now, if this is so, these waves ought to be regularly reflected by a surface… 

The discovery of X-ray diffraction

Starting from the discovery of Roentgen’s X-ray (Röntgen 1895), I here reconstruct the various attempts carried out to find X-ray diffraction using very thin wedge-shaped slits. These experiments

Centennial of X-ray diffraction: development of an unpromising experiment with a wrong explanation

In February 1912 in Munich, P. P Ewald, one of A. Sommerfeld's Ph.D. students, consulted M. Laue on matters related to crystal optics, his thesis subject. During the conversation, Laue conceived the

Application of LEBRA-PXR to the diffraction analysis of minerals

Parametric X-rays (PXR) are a new type of X-ray that are generated by crystal-electron interactions. The Laboratory for Electron Beam Research and Application (LEBRA) at Nihon University generates

It is shown how in 2012, for the first time, on the centennial anniversary of Bragg's law, single atoms have been identified in an electron microscope using X-rays emitted from the specimen, and atomic resolution X-ray maps of a crystal in real space can be formed.

The centennial of X-ray diffraction (1912–2012)

The idea that flashed into Laue’s mind in April 1912 is the very reason for the conference held at the Accademia Nazionale dei Lincei (8–9 May 2012) dedicated to the celebration of the Centennial of

The Imperatives in Atomic Structure Analyses: Lessons from Three-Dimensional Diffraction Gratings, Specular Reflection and Quasi- Crystals

A number of challenges in atomic structure in the coming decades lie where the techniques of the past appear to be wanting. The most notable ‘up to the minute’ exigencies that have taken center stage

An elementary treatment on the diffraction of crystalline structures

Although W. L. Bragg's law can be easily derived for beginners in the field of crystallography, its interpretation however seems to cause some difficulties which lies essentially in the relation

X-Ray Spectroscopy at TEXTOR

Abstract At TEXTOR, an X-ray spectrometer in a Johann mount is utilized to measure the X-ray spectra of He-like elements with intermediate Z. Up to now, the spectra of He-like argon have been

Ninety Years of Powder Diffraction: from Birth to Maturity

The expression “powder diffraction” denotes the phenomenon of diffraction of any electromagnetic waves or particles on polycrystalline (powdered, bulk or thin film) materials which is used in a wide
