Using isosbestic points to extract interactions from structure factors | A. A. Louis
; | Date: |
3 Dec 2002 | Subject: | Soft Condensed Matter; Materials Science | cond-mat.soft cond-mat.mtrl-sci | Abstract: | Inverting scattering experiments to obtain effective interparticle interactions for particles in solution is generally a poorly conditioned problem. 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. | Source: | arXiv, cond-mat/0212073 | Services: | Forum | Review | PDF | Favorites |
