Abstract
| - Bragg reflection amplitudes are examined for the structures P, D, G, C(P), C(D), I-WP, and F-RD inamphiphilic systems. For these ordered phases, a very simple analytical formula for the scattering amplitudesis given. The formula allows determination of the scattering amplitudes for any cross-sectional densityprofile of the membrane decorating the minimal surface. Within this approximation an analytical solutionfor the Debye−Waller factor is presented. Finally we propose a simplified model that can greatly facilitateexamination of the experimental scattering patterns.
