Illustration of the origin of higher-order minima in the absorption correction for a rectangular model with μb = 0.5 and μh = μl = 1. If μb is small enough, incident and diffracted X-rays may penetrate multiple rectangles before hitting the bulk, leading to the observed minima. The geometrically expected angles and the actual angle of the minima do not match exactly due to partial transmission of X-rays through the rectangles. |
