摘要: In recent years, there has been increased research in soft condensed matter. More complex systems, such as polymers, exhibit interesting dynamics over a wide temperature range and broad time scale. order to reproduce this behaviour, combination of model scattering laws the best possible measurements is necessary. By virtue experimental separation incoherent coherent parts, use polarised neutrons with spin polarisation analysis enables confident fitting systems. This argument illustrated by examples from poly (methyl methacrylate) (ethylene oxide).
