"WebScattering / Diffraction. When a crystalline sample is illuminated with x-rays, the x-rays are scattered (diffracted) into very specific directions with various intensities. Detectors are used to measure this “diffraction pattern,” which is then processed by computers to deduce the arrangement of atoms within the crystal. Hard x-rays have ...

In physics and chemistry , Bragg's law, Wulff–Bragg's condition or Laue–Bragg interference, a special case of Laue diffraction, gives the angles for coherent scattering of waves from a crystal lattice. It encompasses the superposition of wave fronts scattered by lattice planes, leading to a strict relation between wavelength and scattering angle, or else to the wavevector transfer with respect to the crystal lattice. Such law had initially been formulated for X-rays upon crystals. Ho… WebApr 11, 2024 · A drawback for gas-phase electron diffraction versus X-ray crystallography is the limitation in size and complexity of the targets.
