Scattering from highly packed disordered colloids.

We discuss the measurable structure factor S(M)(q) of highly concentrated nanoemulsions in a glassy amorphous state. Neutron scattering data show that the primary structure factor peak decreases with increasing concentration and eventually drops below unity. We find very good quantitative agreement between the experimental S(M)(q) and analytical predictions for a polydisperse hard sphere fluid. Subunity structure factor peaks are predicted for dense fluids near and above the jamming transition.
