Limiting sphere in crystallography
NettetA sphere of radius 1/λ is drawn following the recipe below. The Bragg equation is satisfied and diffraction occurs whenever a reciprocal-lattice point coincides with the surface of the sphere. The recipe for constructing Ewald's sphere 2 is as follows (Fig. 1.1.9 ): (1) Draw the incident wave vector s0. http://clay.uga.edu/courses/8550/CM25.html
