Fig. 5: SANS-USANS scattering profiles (left), and Guinier plot (right) for PS clusters in the space sample for four [NaCl] values.

The curves are vertically shifted and superimposed for clarity. In the Guinier region, scattering intensity I(q) is proportional to exp(-Rg2q2),where Rg is the radius of gyration of the clusters, and q is the scattering vector. Rg is obtained as the slope of the plot of log I(q) versus q2.
