摘要：

We compute scattering patterns for six triply periodic minimal surfaces formed in oil/surfactant/water solutions: Three surfaces of a simple topology, Schwarz P (Im (3) over barm), Schwarz D-diamond (Pn (3) over barm), and Schoen G-gyroid (Ia (3) over bard), and three surfaces of a complex topology, SCN1 (Im (3) over barm), CD (Pn (3) over barm), and GX6 (Ia (3) over bard). We show that in the case of the complex structures, scattering intensity is shifted towards the higher hkl peaks. This might cause their misidentification and wrong estimates about the cell size of the structure.
