An intensity correction for pole figure measurements by grazing incident and grazing exit angle X-ray diffraction

In pole figure measurement by X-ray diffraction, the intensity must be corrected for geometric factors entering into the intensity. For the grazing (often, also called glancing) angle diffraction mode, the irradiated area changes with the grazing angle. A theoretical analysis of this effect was made and compared with measured data from a texture-free silver sample. An intensity correction factor is given as the ratio of the detector slit width and the width of the irradiated sample area as seen from the detector. As an application, the texture of thin copper film was studied.
