SPIN-ECHO STUDIES OF MICROEMULSIONS

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