Figure 7.

Illustration of the effect of a change in ν₀ on the agreement of the experimental data with the theoretical predictions of Eq. 6. (Upper) ν₀ = 0.02 s⁻¹, i.e., 10 times smaller than the optimal value used in Fig. 5. (Lower) ν₀ = 0.64 s⁻¹. Both cases correspond to the distance domain 0–100 nm and to Ω² ≈ 5, whereas the minimum of Ω² was found to be 2.39.
