Model of micellar structure tested by SANS and SAXS (from a Kratky camera) in cesium dodecyl sulfate solution

Small-angle neutron-(SANS) and X-ray-scattering (SAXS) patterns obtained at 40 degree C from 0.0729 m D2O solution of cesium dodecyl sulfate (CsDDS) is evaluated in terms of the conventional two-shell model, a three-shell model created for demonstration purposes. Findings suggest that the most reliable information on the aggregate structure is obtained when fitting the four-component model to the combined SANS + SAXS patterns.
