Figure 10
Multispeckle ensemble-averaged intensity–intensity autocorrelation functions [g2(q, t)] from a dilute colloidal suspension of silica particles with a mean radius of 300 nm. Continuous lines are exponential fits with relaxation rate Γ(q). The inset depicts the D0q2 behaviour of Γ(q) with D0 ≃ 0.83 µm2 s−1. |
