Inelastic Scattering of Neutrons by Tritons

Physical Review, 1964
Assuming that the range of nuclear forces is small compared to the size of the triton and the wavelength of the incoming neutron ( zero-range'' approximation), a connection is derived between the cross sections for elastic and inelastic n-t scattering by calculating the ratio of the first Born approximation for inelastic to that for elastic scattering.

Inelastic scattering of neutrons by anharmonic crystals

Solid State Communications, 1963
Recent experiments have been able to observe the widths of the one-phonon resonances in the inelastic scattering of neutrons by crystals. The purpose of this paper is to provide a theoretical framework within which to determine the phonon frequencies and lifetimes from these experiments. When a crystal has anharmonicities interference effects can occur

Quasielastic and inelastic neutron scattering in macromolecular solutions

Physical Review A, 1990
We performed both quasielastic and inelastic neutron scattering, the latter extending to 1000 meV exchange energy, in pure water and in a solution containing 10% lysozyme by weight. The results obtained are discussed in the framework of a structured model of the solution, as given by many previous investigations made with optical techniques.

An Inelastic Neutron Scattering Experiment

American Journal of Physics, 1962
A recording spectrometer model 1820 manufactured by Nuclear Chicago with a NaI crystal scintillator, a neutron source, and an iron scatterer were used to measure the gamma ray at 0.84 MeV from Fe56 by inelastic scattering of fast neutrons.

Inelastic and quasielastic neutron scattering

Current Opinion in Solid State and Materials Science, 1997
Inelastic neutron scattering is a technique for measuring the dynamics of condensed matter on a microscopic scale. Several dynamical regimes can be probed, including atomic momentum distributions, vibrations, and relaxation phenomena. Recent work has been carried out to investigate the dynamics of disordered materials.

Inelastic Scattering of Thermal Neutrons in Graphite

Nuclear Science and Engineering, 1968
The Karlsruhe rotating crystal time-of-flight spectrometer was used to measure the slow neutron scattering law of graphite in a range of energy transfer of 7 to 180 meV and momentum transfer of 1.5...

Quasielastic and Inelastic Neutron Scattering

1982
The neutron is a heavy particle compared to photons and therefore scattering spectroscopy using neutrons covers a unique range of frequency-spatial correlations. For inelastic experiments the far infra-red spectroscopic range up to ∼1000 cm-1 may be observed with sizeable wave vector transfers and phonon dispersion curves mapped out.
