Definitions for "X-Ray Diffraction"
A characteristic reflection and refraction of X-Rays by substances having a regular arrangement of atoms. The phenomenon is used to identify substances having such a structure during petrographic examination.
a technique for establishing the structures of crystalline solids by directing X rays of a single wavelength at a crystal and obtaining a diffraction pattern from which interatomic spaces can be determined
a technique utilizing the characteristic diffraction pattern of x-rays for different crystals.
