SANS results for C12E8 micelles at urea concentrations of 0, 2, 4, 6 and 8 M. a), c), e) C12E8 concentration kept at 29 mM above the CMC at each urea concentration. b), d), f) C12E8 concentration fixed at 61.2 mM. a), b) Scattering spectra. c), d) p(r) curves calculated from each scattering spectrum. e), f) Structure factors calculated for all samples using the hard sphere potential (note expanded scale). The 2 M urea, 61.2 mM C12E8 sample was considered an outlier, and not analyzed.
