Small Angle Diffraction of Light by a Glass Cube

Abstract

Experiments on the diffraction of light by a glass cube failed to yield results compatible with a theory of Halpern and Gerjuoy. Although it is possible that the anomalously large amount of scattering predicted by the theory could have been counteracted by the effects of the clamping of the cube, this seems very unlikely. The remaining alternative appears to be that the use of Born approximation in the theory is unjustified.
