Inelastic neutron scattering (INS) is a spectroscopic technique in which neutrons are used to probe the dynamics of atoms and molecules in solids and liquids. This book is the first, since the late 1960s, to cover the principles and applications of INS as a vibrational-spectroscopic technique. It provides a hands-on account of the use of INS, concentrating on how neutron vibrational spectroscopy can be employed to obtain chemical information on a range of materials that are of interest to chemists, biologists, materials scientists, surface scientists and catalyst researchers. This is an accessible and comprehensive single-volume primary text and reference source.

Experimental Neutron Resonance Spectroscopy deals with the experimental technique of neutron resonance spectroscopy. Pulsed accelerator time-of-flight spectrometers and gamma rays from neutron capture in resonances are discussed. Total neutron cross section measurements are presented, along with neutron scattering and capture cross-section measurements and measurements on fissile nuclides. This book is comprised of five chapters and begins with an introduction to pulsed accelerator time-of-flight spectrometers with moderated continued neutron spectra, together with the pulsed Van De Graaff. Experimental techniques used for neutron cross section measurements, including detectors and data acquisition equipment, are then outlined. Scattering measurements and capture measurements as well as gamma-ray spectra from the capture of neutrons in resonances are considered. The final chapter focuses on the detailed and varied experiments that have been performed on the complicated fission process, together with the parameters of the resonances of the fissile nuclides. This monograph will be a useful resource for spectroscopists and physicists.

Modulation spectrometry of neutrons refers to a measuring principle, characterized by classification of neutron histories in a probabilistic way, not the usual deterministic way. In order to accomplish this, neutron beams entering the sample are modulated by high-transmission, white-beam selectors of the multislit type, such as Fourier or statistical choppers or high-frequency-modulated spin-flippers. In this scheme it is impossible to decide in a unique way through which particular slit any single neutron passed, but the distribution of histories for a large population of neutrons can nevertheless be correctly obtained, by classifying each conceivable history either as a high-probability or as a low-probability event, based on the actual observed state of the neutron selector. So far the principle has been successfully applied to powder diffraction, but it seems to offer extra degrees of freedom if applied to measuring dispersion curves of coherent excitations, such as phonons in single crystals.
