Abstract: Multicomponent systems are of great interest because of their rich variety (structures, interactions, complexities, etc.). Quantitative studies on multicomponent systems with scattering method, however, are quite tricky. Due to overlapping of the scattering signals from each component, the data analyses of scattering patterns from multicomponent systems are attended with much difficulty. We can overcome this problem with the aid of contrast variation. With neutrons as probe, hydrogen/deuterium replacement can be used to modify the "visibility" of different components in the system. Moreover, the fine application of the contrast variation may lead to decompose the scattering signals into partial scattering functions, which allows us to evaluate each component in detail. Especially, the cross-terms can be achieved by means of this technique, which directly reflect the interaction of the corresponding two components. In this manuscript, experimental procedure of the contrast variation small angle neutron scattering as well as a theoretical basis for understanding of the partial scattering functions (both self-terms and cross-terms) are briefly described.
