More accurate potentials can be obtained through the use of isosbestic points, values of k where the scattering intensity I(k) or the structure factor S(k) is invariant to changes in potential well-depth. These points also suggest a new extended corresponding states principle for particles in solution based on the particle density or packing fraction, the second osmotic virial coefficient, and a new measure of potential range.4 pages, 5 figuresSoft Condensed MatterMaterials Sciencetext
