The SANS data analysis enables us to directly compute the average Gaussian and square mean curvatures of the interface in a bicontinuous porous structure. It was applied to 18 different CiEjD20/ n-alkane microemulsions at the respective minimal specific surface points. Summarizing all the measured curvatures as a function of the surfactant volume fraction; we found parabolic dependencies between the interracial curvatures and the surfactant volume fraction at the minimal specific surface point. This method can be applied to SAXS data equally well; We are grateful to the Cold Neutron Research Facility at NIST for neutron beam time. This research was supported by a grant from the Material Science Division of the US DOE;
