Direct methods for the analysis of lamellar neutron diffraction from oriented multilayers: a difference patterson deconvolution approach

A direct method is described 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. 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, and to cases in which isotopic labeling is used instead of partial H2O--D2O exchange
