(a) The influence of the contrast ratio ρR/ρ0 on the principal-peak value SM(Qmax) for spheres with a linear contrast gradient, for polydispersities in a range between 5 and 25% at a total volume fraction of φ = 0.5. The horizontal dashed lines mark, for comparison, the height of the principal peak of the average structure factor 〈S(Qmax)〉. The distinction between the different introduced contrast regimes from Fig. 2 is indicated by the vertical dashed lines. (b) Relative deviation between SM(Qmax) and 〈S(Qmax)〉 for an enlarged region. |
