We have described here a direct method for the solution of the phase problem for lamellar neutron diffraction from hydrated oriented multilayers of model membranes. As a result, the neutron-scattering profiles of such model membranes can be uniquely determined. We note that such methods can easily be extended to cases in which the thickness of the water layer w is somewhat greater than d/2 as long as it is substantially less than d [e.g., w less than 3d/4 would suffice, since deltaP(-d/4 less than or equal to x less than or equal to d/4) would contain only contributions from see article without overlapping contributions from see articles and to cases in which isotopic labeling is used instead of partial H2O-D2O exchange.
我们在此描述了一种直接求解来自模型膜水合取向多层膜的层状中子衍射相位问题的方法。结果，此类模型膜的中子散射轮廓能够被唯一确定。我们注意到，只要水层厚度w实质上小于d，这些方法就能轻松扩展到水层厚度w略大于d/2的情况[例如，w小于3d/4就足够了，因为δP（-d/4≤x≤d/4）将仅包含来自见文章的贡献，而不会与见文章的贡献重叠]，并且能扩展到使用同位素标记而非部分H₂O-D₂O交换的情况。
