We discuss one particular case of spherical particles forming a hard gel with cubic. We extract from the data the one- and two-dimensional structure factors, S(q) and S(q,phi). The experimental S(q) corresponds up to the 9th order Bragg peak to that calculated numerically for a randomly-oriented, finite-size BCC crystal. The concentration dependence of the structural parameters reveals that the dilution law predicted for the center-to-center distance of the spheres is confirmed experimentally while the size of the spherical objects does not follow theoretical predictions due to chain extension with increasing concentration.
