Diffraction intensities from a cluster of helical crystallites

Abstract

Abstract A general expression for the intensity of x-rays diffracted by a conglomeration of identical discontinuous, axially parallel, helical crystallites has been derived. The approach is simple and without involving any simplifying assumptions. A parameter l 0, designating the layer lines, has been introduced into the final expression for the intensity. Some numerical computation has been carried out to study the intensity-distribution pattern along layer lines.
