Experimental and Theoretical Studies on X-ray Plane Wave Images of a Dislocation in the Laue Case

Abstract

Dedicated to Prof. Hildebrandt on the occasion of his 60th birthdayPlane wave images of a dislocation in a silicon crystal were observed with (404) diffraction of MoKai over a wide angular range. The fine structures consisting of five kinds of sub-images and their angular dependences were well simulated by the wave theory taking into account the finite angular spread and pc'arization states of the incident beam. The mechanism of the image formation is studied in terms of interbranch scattering, Eikonal theory and kinematical diffraction.
