Small angle scattering of x-rays
WebbTitle: SMALL-ANGLE SCATTERING OF X-RAYS Full Record Other RelatedResearch Abstract of x rays are discussed. The experiments made to reduce the long exposure time by bending crystals spherically so that they are double-focussiang are described. Two different methods of bending crystals were employed. Webb23 mars 2016 · Grazing-incidence small angle X-ray scattering Incident X-ray beam goes into the sample surface at a very shallow angle α i (normally less than 1°). Scattering is measured with a two-dimensional detector as a function of the exit angle α f (out-of-plane angle) and the in-plane angle 2 Θ.
