Book Description
Inelastic neutron scattering is a well established and important technique for studying the dynamical properties of condensed matter at the atomic level. Often, as is the case of experiments designed to study motions of hydrogen atoms, or magnetic excitations, it may yield information obtainable in no other way. Our aim in assembling this book is to produce an overview of some research topics which have come to the fore recently with the development of high neutron fluxes and high performance inelastic scattering spectrometers. The topics dis cussed here are, by and large, developing rapidly and have not reached the stage at which definitive accounts are always possible. Authors have not therefore attempted to make an extensive review of their topic, and the papers quoted in the text are, in general, those which are seen as having been important in its develop ment (they date, roughly, from the 1971 IAEA conference on neutron scattering held in Grenoble). Basic phenomena are illustrated for the most part by the discussion of one, or two, typical examples. The authors hope that the book will be useful to researchers who are not yet fully aware of the diverse range of problems to which the technique can be applied, and to students beginning research work. For this reason, the first chapter by S. w.

Book Description
A study of si(s) curves as a function of temperature, as well as the energy distribution of the scattered neutrons, affords a way in which to construct a model describing the motion of atoms in a liquid.

Book Description
The purpose fo this book is to present a comprehensive account of the physical concepts and theoretical approaches developed for the study of the dynamical properties of liquids (or more generally, of high-density fluids) at a microscopic level. After a discussion of the basic dynamical phenomena to be interupted, as well as of the various experimental probes, the book gradually exposes the reader to the sophisticated theoretical techniques needed for a satisfactory account of both single particle and coleective motions. The complications are faced in a stepwise fashion, with special attention to the physical content of the results. As a result of the progress achieved in the last decade, in the end a satisfactory understanding of most of the phenomena characterizing this fascinating field emerges.

Book Description
This thesis presents neutron scattering data that contribute to the understanding of four distinct areas of condensed matter physics, including iso-compositional liquid-liquid phase transitions and the glass formation in rare earth doped BaTi2O5. In situ aerodynamic levitation with laser heating was combined with neutron scattering in order to study both liquid-liquid phase transitions in (Y2O3)x(Al2O3)1-x and the atomic and magnetic ordering in liquid Invar. Among several significant results, obtained in this case from small angle neutron scattering, was the absence of a phase transition across a range of temperatures and compositions in the yttria aluminates. As these are a principal system in which liquid-liquid phase transitions have been hypothesized, this is an important contribution in a contentious area.

Book Description
An Introduction to the Liquid State focuses on the atomic motions and positions of liquids. Particularly given importance in this book are internal motion of molecules as a whole and the motion of atoms in a monatomic liquid. Divided into 16 chapters, the book opens by outlining the general properties of liquids, including a comparison of liquid argon and liquid sodium, discussions on theories and methods of studying the liquid state, and thermodynamic relationships. The book proceeds by defining the molecular distribution functions and equation of state, the potential function for non-conducting liquids and metals, and measurement of pair distribution function. Numerical analyses and representations are provided to simplify the functions of equations. The book discusses equilibrium properties wherein calculations on the state of gases and fluids are presented. The text also underlines space and time dependent correlation functions. Given emphasis in this part are neutron scattering, electromagnetic radiation, and various radiation scattering techniques. Other concerns discussed are diffusion and single particle motion, velocity of correlation function, diffusion and viscosity coefficients, liquid-gas critical point, and a comparison of classical and quantum liquids. The selection is a valuable source of information for readers wanting to study the composition and reactions of liquids.
