Small-angle neutron scattering is used to investigate the structure of single-phase AOT (sodium di-2-ethylsulfosuccinate)/D2O/decane microemulsions containing equal volumes of water and oil and a variable concentration of surfactant. Each scattered-neutron spectrum exhibits a pronounced interaction peak. As the volume fraction of AOT is increased from 0.18 to 0.42, the peak position shifts to larger values of Q, and the peak height diminishes. The spectra are consistent with an ordered droplet phase, as opposed to a bicontinuous structure (Refer to PDF file for exact formulas).
