Spin echo studies of microemulsions

Abstract

Neutron spin echo (NSE) can be employed to study the dynamics of a variety of microemulsion phases. Starting from the droplet phase, we will show what can be measured by coherent quasi-elastic neutron scattering with special emphasis on model independent information. Combining the well known contrast variation method of small angle neutron scattering (SANS) with the unique energy resolution of NSE we can separate motion which are otherwise undetectable. Combining the static and dynamical experiments, microscopical parameters like bending rigidity ( K) can be deduced via model fitting.
