Neutron Scattering: Treatise on Materials Science and Technology, Vol. 15, Volume 15G. Kostorz Treatise on Materials Science and Technology, Volume 15: Neutron Scattering shows how neutron scattering methods can be used to obtain important information on materials. The book discusses the general principles of neutron scattering; the techniques used in neutron crystallography; and the applications of nuclear and magnetic scattering. The text also describes the measurement of phonons, their role in phase transformations, and their behavior in the presence of crystal defects; and quasi-elastic scattering, with its special merits in the study of microscopic dynamical phenomena in solids and liquids. Special materials problems in neutron devices are also considered. Materials scientists, solid state physicists, physical chemists, and metallurgists will find the book invaluable. |
