Preliminary Experimental Study of New Diffraction Maxima in X-Ray Photographs

Abstract

A revised theoretical treatment of the diffuse scattering of x-rays by crystals predicts a rapid variation of intensity with scattering angle, thus leading to intensity maxima in specific directions. The new diffraction maxima were observed with a rocksalt crystal and $\mathrm{Cu} K\alpha$ radiation. The peak intensities and the half-widths were studied as functions of the direction of incidence. The observations were found to be in general agreement with theory.
