Direct observation of forward diffracted beam from imperfect and thin natural diamond crystals

A diffracted beam in the forward direction has been directly observed in imperfect (diffraction curve half widths: ∼ 100″ -2- ∼ 300″) and thin (μt sec θ: ∼ 0.1 – ∼ 0.3) type II natural diamond crystals. A five crystal X-ray diffractometer was employed in (+,−,+) setting. The intensity of the forward...

Description
Summary:A diffracted beam in the forward direction has been directly observed in imperfect (diffraction curve half widths: ∼ 100″ -2- ∼ 300″) and thin (μt sec θ: ∼ 0.1 – ∼ 0.3) type II natural diamond crystals. A five crystal X-ray diffractometer was employed in (+,−,+) setting. The intensity of the forward diffracted beam decreased with the degree of imperfection. However, diffraction curve half width of ∼ 300″ is nearly the limit for observation.
