Frontiers Of Neutron Scattering

This book provides ideas on what neutron scattering could look like in the next millennium. In particular, nonconventional, unusual or innovative neutron scattering experiments (from both the scientific and the instrumental point of view) are described which either have novel applications or provide a new insight into science and technology. Chapters on theoretical aspects are adequately included. The scientific and technical areas cover the following topics: novel neutron scattering techniques and perspectives in neutron scattering instrumentation (including sample environment); soft condensed matter, particularly colloids and polymers; materials science and industrial applications; structure and dynamics of multilayers and nanocrystalline materials; dynamical aspects and quantum effects in molecular magnets; strongly correlated electron systems, with emphasis on dynamic correlations in low-dimensional magnets. All these topics are thoroughly introduced and discussed by acknowledged experts.

Neutron scattering has become a key technique for investigating the properties of materials on an atomic scale. The uniqueness of this method is based on the fact that the wavelength and energy of thermal neutrons ideally match interatomic distances and excitation energies in condensed matter, and thus neutron scattering is able to directly examine the static and dynamic properties of the material. In addition, neutrons carry a magnetic moment, which makes them a unique probe for detecting magnetic phenomena. In this important book, an introduction to the basic principles and instrumental aspects of neutron scattering is provided, and the most important phenomena and materials properties in condensed matter physics are described and exemplified by typical neutron scattering experiments, with emphasis on explaining how the relevant information can be extracted from the measurements.

This book provides an introduction to the basic principles of neutron scattering and its application to current problems in condensed matter science and technology. Experiments on novel materials are particularly emphasized.

Neutron Scattering

Much of what we know about atoms, molecules, and the nature of matter has been obtained using spectroscopy over the last one hundred years or so. In this book we have collected together twenty chapters by eminent scientists from around the world to describe their work at the cutting edge of molecular spectroscopy. These chapters describe new methodology and applications, instrumental developments, and theory which is taking spectroscopy into new frontiers. The range of topics is broad. Lasers are utilized in much of the research, but their applications range from sub-femtosecond spectroscopy to the study of viruses and also to the investigation of art and archeological artifacts. Three chapters discuss work on biological systems and three others represent laser physics. The recent advances in cavity ringdown spectroscopy (CRDS), surface enhanced Raman spectroscopy (SERS), two-dimensional correlation spectroscopy (2D-COS), and microwave techniques are all covered. Chapters on electronic excited states, molecular dynamics, symmetry applications, and neutron scattering are also included and demonstrate the wide utility of spectroscopic techniques. * provides comprehensive coverage of present spectroscopic investigations * features 20 chapters written by leading researchers in the field * covers the important role of molecular spectroscopy in research concerned with chemistry, physics, and biology
