The method of synchrotron radiation small-angle X-ray scattering (SR-SAXS) has been used to obtain structural ;nformation on the system of bis2(2-ethylhexyl) sulfosuccinate (AOT)/ H₂O/isooctane. By using the Guinier plot (Ln I (q) versus q² ) on the data sets in a defined small q range (0.03-0.06Å^-1), the gyration radius at different water/surfactant molar ratio, W₀, was obtained. With the increase of W₀, the gyration radius (R_g) increased at the range of 23.2~52.7 Å.
