In crystallography, the reciprocal lattice of a Bravais lattice is the set of all vectors K The reciprocal lattice plays a fundamental role in most analytic studies of periodic structures, particularly in the theory of diffraction For Bragg reflections in neutron and X-ray diffraction, the momentum одумб difference between incoming and diffracted X-rays of a crystal is a reciprocal lattice vector The diffraction pattern of a crystal can be used to determine the reciprocal vectors of the lattice Using this process, one can infer the atomic arrangement of a crystal.  Orlando2010 г Мягкая обложка, 168 стр ISBN 6130346522.
