Principles of X-ray diffraction

When a beam of monochromatic X-rays is incident on a crystal, since the crystal is composed of cells with regularly arranged atoms, the distance between these regularly arranged atoms is of the same order as the incident X-ray wavelength, so X-rays scattered by different atoms Interference produces strong X-ray diffraction in certain special directions. The orientation and intensity of the diffraction lines in space are closely related to the crystal structure. This is the basic principle of X-ray diffraction.
