Laue condition

Laue condition

A condition for a wave of an atomic scale wavelength, such as X-ray, electron and neutron, to cause diffraction by a crystal lattice. The "Laue condition" is equivalent to the Bragg condition. The Bragg condition is an instinctive scalar expression in the real space. On the other hand, the Laue condition is a vector expression in the reciprocal space, which is indispensable for advanced theoretical treatment of diffraction.
