Abstract

Spectroscopic techniques are widely used for the investigation of several types of systems. These techniques are based on the several types of interaction of the used radiation with matter, which, on the other hand, depends on the intrinsic characteristics of the radiation and its energy. A wide class of spectroscopic methods is the scattering methods: light scattering, X-ray scattering and Neutron scattering. In these cases the experimental data can provide interesting structural information about the studied system as, for example, particle shape and its internal structure, overall structural arrangement of particles, response to the variation of environmental conditions as temperature, pH, ionic strength, etc. However, one of the main difficulties when using scattering methods is the analysis and interpretation of the results. In a previous project, we started the development of methods for simulation, analysis and modeling for small angle scattering and diffraction data. These methods were successfully applied in a broad range of applications, permitting the correct analysis and description of experimental data as well as the retrieval of correct structural parameters. As a result, a set of tools is under developed and is made available for the scientific community. In this project is proposed the development of of new modeling tools and the enhancement of the developed methods. Also, the modeling methods will be extended for the investigation of oriented systems. As described in this project, this approach is scarce in the literature and will allow the achievement of original results on a number of systems. (AU)
