The Inelastic Scattering of Neutrons
Physical Review, 1952The total cross section and the differential cross section for the inelastic scattering of neutrons are considered. It is assumed that the compound nucleus is sufficiently excited so that the statistical model may be applied. If the statistical model may be applied as well to the residual nucleus, it is shown that the angular distribution of the ...

Inelastic Neutron Scattering, Applications
1999The application of both coherent and incoherent neutron scatting techniques to problems in chemistry, physics, engineering catalysis and polymers is described. The various different types of structural and dynamic molecular information that can be obtained are illustrated.

Inelastic Neutron Scattering from Anisotropic Superconductors
Journal of the Physical Society of Japan, 2002The magnetic fluctuation spectra are calculated for various phases of anisotropic superconductors. Both singlet and triplet superconducting phases can support antiferromagnetic fluctuations for small values of the Coulomb repulsion, the spectra show power law frequency dependencies due to the nodes in the superconducting order parameter.

Inelastic Neutron Scattering With Fission Neutrons
Canadian Journal of Physics, 1971A detailed investigation has been conducted of the usefulness of fission-spectrum neutrons for inelastic neutron scattering studies. A Ge(Li)–NaI(Tl) annular pair spectrometer was employed in conjunction with a versatile in-core irradiation facility to conduct this evaluation.

1986
Experiments with thermal neutrons are most useful in the study of lattice vibrations. The advantage stems from the basic nature of the neutron: The De Broglie wavelength of a thermal neutron is of the same order of magnitude as the interatomic distances in crystals, and the energy of a thermal neutron is of the same order as the energy of a lattice ...

Inelastic neutron scattering in SeTe glasses
Journal of Non-Crystalline Solids, 1990Abstract Inelastic neutron scattering has been used to study the excitation spectra g(E) of a series of four SexTe1−x glasses, with x = 0.95, 0.90, 0.80, 0.70, at two temperatures, 100K and 200K. The low frequency spectra show a breakaway from an (energy)2 dependence for g(E) to a higher power dependence, which is typical of the density of states for

Inelastic neutron-deutron scattering
Nuclear Physics A, 1969Abstract A theory of the charge exchange process d(n,p)2n is presented which is based on an earlier theory of slightly inelastic proton-deutron scattering. Calculations of the 150 MeV measurements of Measday are found to be in good agreement with experiment for protons scattered through 20° or less.

Inelastic neutron scattering spectroscopy
2009Abstract In the previous chapter, we have seen how coherent inelastic neutron scattering can be used for the study of collective excitations, such as phonons and magnons, in single crystals. This spectroscopic technique was pioneered in the 1950s by the Canadian physicist, Bertram Brock-house, and much of the earlier work was confined to

Inelastic neutron scattering in Nb93
Nuclear Physics, 1959Abstract Study of gamma ray spectra following inelastic neutron scattering in Nb 93 has been made at bombarding energies ranging from 0.81 to 2.25 MeV. Measurement of thresholds for the gamma rays and the gamma-gamma coincidence spectra has enabled us to work out a level scheme for Nb 93 . The energies of the two levels previously reported have been
