Divergent Beam X-Ray Photography with Standard Diffraction Equipment

Abstract

A new method for preparing divergent beam x-ray photographs of crystals is presented. This employs the usual Laue transmission camera and a collimated primary beam of x-rays. Fluorescent radiation originating either in the crystal sample or at a radiator in front of the crystal is used as the source of divergent x-rays. Some applications of the technique to determinations of orientation, lattice parameters, and crystal perfection are illustrated.
