- noun the diffraction of X-rays arising due to the position and size of the atoms within a crystal, used to obtain structured information about a crystal
- The diffraction by a crystal of an incident X-ray beam. The angles at which the X-rays are diffracted are determined by the interatomic distances within the lattice, with the resulting characteristic pattern enabling the determination of the structure of the crystal. Such diffraction is the basis of X-ray crystallography.
