Multispeckle intensity–intensity autocorrelation functions from a concentrated aqueous colloidal suspension of silica particles (mean radius Rs ≃ 126 nm and volume fraction ϕs ≃ 0.43) for different acquisition times at the structure factor peak (0.0216 nm−1) and above. Continuous and dashed lines are exponential fits to the initial and final decays of g2(q, t), respectively. |
