Abstract
Algorithms are presented to correct intensities affected by divergence slit attenuation in the low 2θ region of Bragg–Brentano powder diffractometers with rectangular sample holders. The intensity loss below a limiting angle 2θ1 occurs when the X-ray beam cross section exceeds the sample surface at decreasing angles. For identification purposes, the observed intensities can be scaled up to values comparable with intensities unaffected by divergence slit effects.Keywords
