Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

Researchers have taken atomic diffraction to a new level, revealing surprising behaviors in high-energy helium and hydrogen ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

In this research, scientists used the relativistic ultrafast electron diffraction (UED) instrument to observe the relaxation of photoexcited o-nitrophenol. Then, they used a genetic structure ...

Specially made diffraction gratings use optical laser light to illustrate how wave-based material characterization techniques work, such as X-ray diffraction, electron diffraction, and neutron ...
