The time evolution of g2(q, t) along q for a suspension of silica particles (RS ≃ 300 nm and σR ≃ 5.4 nm) with ϕ ≃ 0.014. (a) At 70 s after shaking, illustrating the signature of velocity fluctuations (oscillations after the initial fast decay). (b) At about 2000BB1 s when the suspension had returned to Brownian dynamics as characterized by a slower exponential decay. Note the differences in the q dependence and decay time between the two plots.
