Simultaneous Monte Carlo Determination of Particle Size Distribution and Pair-Correlation Function of Spherical Colloids from a Diffraction Experiment

摘要: A new simulation method was developed in which both positions and radii of the particles are treated as variables a reverse Monte Carlo-like procedure. The can be used evaluation diffraction data on one-component spherical colloids, where polydisperse feature cannot neglected. It reproduces target functionthe measured scattered intensitieswell, without priori knowledge parameters supposed Schulz distribution particle size. is successful at wide range densities, but it fails very dense systems broad Small-angle neutron light-scattering polystyrene colloids were evaluated by compared to using monodisperse assumption, contact pairs observed. good reproduction experimental achieved no found agreement with theoretical other results.
