Description

The structure and fluctuations of membranes such as phospholipid vesicles or microemulsions is experimentally accessible with small angle neutron and x-ray scattering (SANS and SAXS) and neutron spin echo spectroscopy (NSE). A mathematical model is developed which jointly analyzes SANS, SAXS and NSE data within a single framework. As an example, scattering data from unilamellar vesicles [1] and from microemulsions [2] will be presented.
