Small-Angle Scattering (Neutrons, X-Rays, Light) from Complex Systems

This book addresses the basic physical phenomenon of small-angle scattering (SAS) of neutrons, x-rays or light from complex hierarchical nano- and micro-structures. The emphasis is on developing theoretical models for the material structure containing self-similar or fractal clusters. Within the suggested framework, key approaches for extracting structural information from experimental scattering data are investigated and presented in detail. The range of parameters which can be obtained pave the road towards a better understanding of the correlations between geometrical and various physical properties (electrical, magnetic, mechanical, optical, dynamical, transport etc.) in fractal nano- and micro-materials.

Provides a unique in-depth description of the structure of self-similar systems at nano and micro scales Brings together stochastic and deterministic approaches to address the much debated issue of fractal modeling Offers step-by-step instructions on how to extract structural parameters from small-angle scattering data
