The Theory of Neutron Scattering from Condensed Matter (The ^AInternational Series of Monographs on Physics)

An invaluable, up-to-date reference aid for investigators and researchers, this two-volume work develops the principles and concepts of statistical physics and quantum chemistry that are the basis for the interpretation of experimental data. These volumes build on the author's now standard text, Theory of Neutron Scattering (Oxford University Press, 1971), and include expanded coverage of nuclear scattering, with many sections completely rewritten and updated, and many previously unpublished experimental calculations. With a greatly expanded bibliography including 200 new references, this work will interest graduate students and researchers in physics.

Interesting and new specific results of current theoretical and experimental work in various fields at the frontier of particle scattering and X-ray diffraction are reviewed in this volume. Special emphasis is placed on the study of the microstructure of solids, crystals and liquids, both classically and quantum mechanically. This gives the reader essential insights into the dynamics and properties of these states of matter. The authors address students interested in the physics of quantum solids, crystallography and material science as well as physical chemistry and computational physics.
