Neutron, X-ray and Light Scattering: Introduction to an Investigative Tool for Colloidal and Polymeric Systems : Proceedings of the European Workshop on Neutron, X-Ray and Light Scattering as an Investigative Tool for Colloidal and Polymeric Systems, Bombannes, France, 27 May-2 June, 1990Peter Lindner, Thomas Zemb This book is devoted to a simple practical approach to neutron, X-ray and light scattering experiments, involving model calculation of the scattering and mathematical transformation. It is intended to attract colloid and polymer scientists using scattering methods in their laboratory or at common research facilities. The primary objective is to explain the current methodology of elastic and quasi-elastic scattering techniques (avoiding both under and over-exploitation of data) rather than a general course on colloids and polymers. Basic information on data interpretation, on the complementarity of the different types of radiation, as well as information on recent applications and developments are presented. |
