Methods of X-ray and Neutron Scattering in Polymer Science presents the basic theories underlying x-ray and neutron scattering-two of the most powerful tools for characterizing materials-and also covers the various techniques that have been developed for their application to the study of polymers. While there is a great deal of similarity between the x-ray and neutron scattering methods, the two were developed in different time periods by different groups of scientists, and as a result very distinct terminologies evolved to explain the same phenomena. In this unique text the two are presented together from the very beginning, with a consistent set of symbols and terminologies, so that students can become equally familiar with both from the outset. Also, to help students gain a unified view of diffraction, the distinction between wide-angle diffraction and small-angle scattering is postponed until late in the text.
