We exemplarily investigate how optical properties of single scatterers in interacting multi-particle systems influence measurable structure factors. Both particles with linear gradients of their scattering length density and core-shell structures evoke characteristic deviations between the weighted sum $\langle S(Q)\rangle$ of partial structure factors in a multicomponent system and experimentally accessible, measurable structure factors $S_{\mathrm{M}}(Q)$. While $\langle S(Q)\rangle$ contains only structural information of self-organising systems, $S_{\mathrm{M}}(Q)$ additionally is influenced by optical properties of their constituents resulting in features such as changing amplitudes, additional peaks in the low wavevector region or splitting of higher-order maxima which are not related to structural reasons. Hence, a careful data analysis regarding size-distribution and optical properties of single scatters is mandatory to avoid a misinterpretation of measurable structure factors. |
