✦ Synopsis

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 those occurrmg in a closed shell. Thus excludes the possibihty that the microemulsion structure is a dispersion of disconnected, albeit closely packed, droplets of equal size, but is consistent with the formation of connections between oil and water domains such as would occur in a locally ordered bicontinuous structure.
