Contrast and Contrast Variation in Neutron, X-ray, and Light Scattering
The concept of scattering contrast is central to (small-angle) scattering of neutrons, X-rays, and visible light, as it defines the visibility to the radiation of the nano- and mesostructures under scrutiny, in their respective solvent or matrix. In this chapter, we start with the scattering process by elementary scatterers, such as nuclei or atoms, which produce secondary, scattered waves, and th
