โฆ Synopsis
Neutron small-angle scattering has been used to study the structure of an oil in water microemulsion in the critical region. The structure. one of small "swollen" micelles. is independent of the critical fluctuations. This together with other evidence strongly suggests that the latter are clusters of swollen micclles.

Small-angle neutron scattering has been used to determine whether or not a microemulston, contaming equal volumes of oil and water, has a bicontinuous structure. The spectrum. from the interfacial layer of surfactant and co-surfactant. shows the presence of distances both longer and shorter than tho
