This graduate-level text reviews the field of critical phenomena, including the use of neutron scattering techniques as an aid in their study. The book introduces the principles of magnetic systems and their critical dynamics, outlining the experimental and theoretical methods that have been used to understand the scattering effect. Measurements are examined for the dynamics and statics of one-, two-, and three-dimensional systems. Multicritical effects, critical phase transitions in magnetic metals, dilution, percolation, and random-field effects are also discussed in the light of neutron...

The application of neutron scattering to polymers provides information which cannot be obtained by other techniques and has allowed progress in our understanding of polymer conformation in the bulk. This book presents examples which are needed to understand how these techniques can be applied. It is specifically written to introduce the newcomer and non-expert in physics or chemistry to the experimental techniques and the basic theory necessary to understand the results.

This book provides an account of the calculation of the matrix elements of the magnetic interaction operator, extracting important, useful results from mathematical analysis. The authors give a complete theory of nonrelativistic magnetic neutron scattering with various tables listing nj symbols, fractional parentage coefficients, and various other quantities that arise naturally in the theory. Subsequently, the book takes account of the growing interest in magnetic photon scattering realized by synchrotron photon factories and contains an appropriate theory. While the treatment centers on...

Liquid 4He and 3He are the purest Bose and Fermi liquids currently found in nature. Understanding their dynamics is fundamental to understanding more complex matter. This book provides an introduction to the subject and develops the theory of zero sound, phonons, rotons, spin and single particle excitations in quantum solids and fluids. Similarities between quantum solids and fluids are drawn wherever possible. Topics include dynamic response functions, neutron studies of solid helium, the nature of excitations in 3He, approximations to the dynamic susceptibility, and intermediate and high...

Slow-moving, low-energy ultracold neutrons provide an important tool for investigations in physics. They can be kept in hermetically sealed vessels for up to 15 minutes before they decay, allowing researchers sufficient time to observe the action of very weak fields and yielding valuable insights into neutron properties. In addition to describing how these particles are produced, detected, and analyzed, this book provides coverage of improvements in the techniques of ultracold neutron science--with information on how physicists may increase storage times--and explores ways they can be used...

With order and disorder playing such an important role in modern condensed matter physics research, this book provides new insight into a vital technique used to inform physicists about the nature of magnetic materials: neutron scattering. Hicks presents a comprehensive treatment of the benefits of neutron scattering in the field of magnetism, the current state of knowledge of this technique, and what it can tell researchers in magnetism and disordered materials in condensed matter physics about these increasingly important materials.

This book details the physical concepts and theoretical approaches developed to study the dynamical properties of high-density fluids at the microscopic level. After an incisive discussion of basic dynamical phenomena and various experimental probes, the book introduces the sophisticated theoretical techniques necessary for obtaining an in-depth account of both single particle and collective motions. Potential complications are addressed in a stepwise fashion, with special attention paid to the physical contents of the results. Well-written and comprehensive, Dynamics of the Liquid State will...

Quasielastic neutron scattering has made many important contributions to the atomistic elucidation of diffusion processes in solids. The aim of this book is to inform researchers in solid state physics, solid state chemistry, and inorganic materials science of the potential of quasielastic neutron scattering. It has been written in two sections for experimentalists. The first part contains theoretical background on neutrons, neutron scattering, and solid state diffusion, which is essential for the proper use of quasielastic neutron scattering; the second part of the book summarizes the...

This is a completely revised and rewritten edition of a popular postgraduate physics text originally published 25 years ago. While the general content and style of this edition follow that of the original, the book now reflects the enormous expansion of theoretical and experimental research that has taken place over the past quarter of a century. The book provides an excellent introduction to the liquid state. It aims to cover the simpler and more basic parts of this vast topic while preserving a balance between different areas. The author breaks the subject down by liquid state topic rather...

This is the first comprehensive account of diffuse neutron scattering, a unique tool for determining structural disorder in solids. The text takes the reader through theoretical, computational and experimental developments in the subject and describes in detail its application to a number of structural disorder problems. These include the more traditional subjects of substitutional disorder in alloys and orientational disorder in molecular systems as well as the more recent studies of superior and framework materials. Particular emphasis is placed on recent refinement methods for data...
