Figure 5
Normalized intensity autocorrelation functions in SP (a) and MP (b) mode. The normalized g⁽²⁾ functions of experiments and corresponding fits of equation (3)

to the data are shown by dotted, square and dashed lines in (a) and (b). The inset shows combined measured data from the SP and MP modes together with the corresponding g⁽²⁾ functions calculated for particles with R = 179 nm. (c) The extracted τ_c from (a) and (b) as a function of Q. The dashed line shows a fitting curve of $[\tau_{\rm {c}}^{-1} = D_{0}Q^{2}]$ .
