X-ray diffraction

X-ray diffraction
X-ray diffraction n a scattering of X-rays by the atoms of a crystal that produces an interference effect so that the diffraction pattern gives information on the structure of the crystal or the identity of a crystalline substance

* * *

a technique for studying the cell based on the diffraction of radiations when they encounter small obstacles; used especially in the study of inorganic and organic crystals, in which it is possible to determine the precise spatial relationships between the constituent atoms.
