Figure 4.

Typical ensemble averaged g ₂(q, t) functions at different q values (a) before and (b) after turning on the UV light for a sample containing 4% H₂O₂, and (c) for 12% H₂O₂ with the UV light on. The continuous lines are fitted curves using (a) equation (1) with the exponential term, and (b) and (c) equation (1) with equation (3). The main parameters are indicated in the legend.
