RSoXS

Resonant Soft X-ray Scattering (RSoXS) is a kind of resonant scattering that uses relatively low-energy x-rays. These 'soft' x-rays are well-matched to the absorption edges of light elements (C, N, O, etc.) and thus RSoXS can yield substantially improved signal-to-noise for organic materials. Moreover, multi-components systems can be analyzed by tuning the x-ray energy to different absorption edges; by comparing scattering patterns obtained at different energies, the spatial distribution of different sub-components can be resolved.
