The small angle X-ray scattering from alternating lamellar phases may formulated on the basis of two concepts. The one is that the scattering is due to positive and negative density deviations from the average density of the system and the other is that the scattering depends upon the excess electron density between the two phases. In order to consider scattering from real systems, the mathematical treatment is carried out for two dimensional lamellar assemblies with orientational distribution. The scattering pattern calculated on the former concept is in good agreement with ones which have been observed experimentally. By contrast, the pattern calculated on the latter concept has many scattering maxima which have never been observed. The origin of this discrepancy for the latter concept has been derived from its scattering equation. |
