With the correction parameter H, the crossover expression assumes a rather complex form. H is given by:

where

The parameters resulting from the crossover correction are:

The three diffusion functions D_total, D_bg and D_crit are shown in Fig. 5.16. The corresponding correlation length is shown in Fig. 5.17.

5.5.3 Relaxation rates Γ_BF^DLS(t)

From the dynamic scaling hypothesis (3.35), the following characteristic relaxation-rate amplitude is obtained for dynamic light scattering (DLS):

Figure 5.18 shows the fit together with the corresponding measured values.
