Abstract

A model free evaluation of small angle scattering data of interacting particles results in real space curves that are often difficult to interpret. It is then easier to use a model for the inter and/or the intra particle effects. Such a procedure requires the selection of appropriate models. The selection of the correct model is facilitated by interpreting parts of the purely model free real space results of the scattering data. The corresponding functions for hard, charged, and attractive spheres are simulated as well as the curves of spheres in BCC crystalline order and of cylinders in hexagonal order. The simulated results are compared to experimental data obtained from concentrated emulsions. Estimations for particle diameter, type of interaction, next neighbour distance, and volume fraction can be deduced from most of the data.
