g₂ functions and relaxation times measured at different wave vector transfers.

(a). g₂ functions at different wave vector transfer measured from the same sample. A total of 150 frames with 100 pulses per frame were recorded at each sample position. The red lines are compressed exponential fits to the experimental data. The obtained relaxation time constants are indicated for each plot. (b). Compressed exponent α obtained from the best fit to the g₂ functions. (c). Corresponding q-dependence of the relaxation time constants (τ). The red line is τ = q⁻¹ for comparison.
