Dynamical Theory of X-Ray Diffraction

The dynamical theory of x-ray diffraction has been advanced by the development of perfect or nearly perfect crystals. Authier (emeritus, U. Pierre et Marie Curie, France) first provides a historical account of developments in the field, from the work of Ewald in the early part of the 20th century onward. He then describes the diffraction properties of plane and spherical waves by perfect crystals. He extends dynamical theory to deformed crystals. Finally, he provides a section on applications, i…
