Figure 7: Dependence on particle size and surface density.
From: Two-dimensional structure from random multiparticle X-ray scattering images using cross-correlations
Data for the 350 nm nanoparticles (left column) and 200 nm particles (right column), and for three different particle surface densities corresponding to N=2.5 (red), N=20 (blue) and N=80 (black). (a) Examples of diagonal 2-point CCs C(2)(q1,q2,ψ), as a function of ψ, for two different q values for each particle size. The data are rescaled with N. (b) Zeroth-order Fourier coefficients s0(q) of the single-particle diffraction pattern, as a function of q. The background signal is represented by the dashed green curve. (c) Amplitude of the Fourier coefficients sn(q) of the single-particle diffraction pattern, as a function of q. The values are shown for n=6 and n=12 and are rescaled with s0(q) calculated from the N=20 data set. (d) Average deviations Δs6(q) of the Fourier coefficients s6(q), as a function of q (Methods).
