Diffracted beam–transmitted beam Borrmann X-ray topography in copper. A novel method of stereo depth topography

摘要

The observed depths of dislocations, as measured from the exit surface of a copper single-crystal, are within a region of the crystal where µd, the kinematic linear absorption coefficient times the depth, is less than or approximately equal to unity. Splitting of the Borrmann wave into its diffracted and transmitted beam components is indicated in relatively perfect portions of the crystal near the exit surface.
