Abstract
Single crystals of an Ia (3) over bard bicontinuous direct cubic phase form ed by a non-ionic surfactant in water are investigated using high-resolved X-ray diffraction. The shape of the Bragg peaks confirms the existence of a 3D long-range order inside the cubic phase. A weak diffuse scattered inten sity signal is measured very near the Bragg peaks. We attribute this signal to thermal diffuse scattering (TDS) and we give an estimation of the contr ibution of elastic waves to this TDS.
