Abstract
A well defined peak in the diffraction curve of the forward diffracted beam has been observed in thin nearly perfect diamond crystals even when µt(absorption coefficient x thickness) was much less than 1. This has been possible due to the application of a sharply defined narrow beam of X-ray which is highly monochromated (Kαl) and collimated. Bulk of the forward diffracted beam has been isolated from the residual direct beam with the help of a precise technique. On the basis of dynamical theory under these experimental conditions, a dip rather than a peak in the diffraction curve of the forward diffracted beam is expected.
