    "abstract": "We present a novel method for analyzing Small Angle X-ray Scattering data on\nmultilamellar phospholipid bilayer systems at full hydration. The method\nutilizes a modified Caille\u0027 theory structure factor in combination with a\nGaussian model representation of the electron density profile such that it\naccounts also for the diffuse scattering between Bragg peaks. Thus, the method\ncan retrieve structural information even if only a few orders of diffraction\nare observed. We further introduce a new procedure to derive fundamental\nparameters, such as area per lipid, membrane thickness, and number of water\nmolecules per lipid, directly from the electron density profile without the\nneed of additional volumetric measurements. The theoretical apparatus is\napplied to experimental data on\n1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine and\n1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine liposome preparations.",
