diffuse XRR
diffuse X-ray reflectance
A method for determining structure by directing a beam of X-rays at an extremely flat surface (at angle theta minus omega to the surface) and measuring the intensity of the X-rays which undergo diffuse reflection (and are emitted at angle theta plus omega from the surface).
