Abstract

Biological lipid bilayer structures have been studied which give neutron diffraction data to better than 0.3 nm resolution. The general problem of phase retrieval in these one- dimensional, centrosymmetric cases was investigated using transform method together with deuterium incorporation (contrast variation) in order to establish experimental procedures of general use for such neutron scattering studies. The findings demonstrate procedures which, in many cases, quickly provide the experimental data necessary for reliable phase retrieval.
