The following important concepts have been illustrated in the previous lectures, but are sum-marised again here1. Real space and real lattice Real-space points are described by means of an origin and real ... WebThe origin of the crystal is at the center of the Ewald sphere, and the incoming X-rays are diffracted from that crystal. The origin of reciprocal space is at the point where the incoming X-ray beam would exit the Ewald sphere. If we rotate the crystal, we rotate the Bragg planes and so we rotate reciprocal space in the same direction. fix it in foil cookbook https://shinestoreofficial.com
