The Inelastic Scattering of Neutrons

Physical Review, 1952
The 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 Scattering of Deuterons

Nature, 1949
WE have recently performed experiments which show that deuterons are scattered inelastically by aluminium and magnesium targets. Such inelastic scattering is well known for protons, but has not hitherto been observed with deuterons.

Direct inelastic scattering of nucleons

Nuclear Physics, 1963
Abstract The forward and backward peakings observed in the angular distributions in nucleon collisions, are interpreted theoretically as forward knock on and heavy particle stripping, processes. Some experimental data on C 13 (p, n)N 13 at varying proton energies were chosen and satisfactory fits were obtained.

Inelastic Scattering by Deformed Nuclei

Physical Review, 1962
The techniques of the sharp and rounded cutoff models for elastic scattering are extended to the calculation of nuclear monopole and quadrupole excitation in the adiabatic approximation. In the case of scattering from nucles with quadrupole deformations, a spheroidal coordinate system is introduced in which one of the coordinate ellipsoids coincides ...

Semiclassical theory for inelastic scattering

Physical Review A, 1989
Presentation d'une theorie simple pour obtenir l'approximation semiclassique pour la diffusion inelastique. Elle donne des expressions explicites pour les valeurs moyennes d'une large classe d'operateurs quantiques, valables en general jusqu'a 0(K), et qui peuvent etre utilisees pour caracteriser la distribution finale d'une particule ...

Inelastic scattering from surfaces

Physical Review B, 1991
Developpement d'une approche de la diffusion inelastique de sondes de basse energie sur des surfaces. Cette approche relie le regime quantique unique et nul au regime multiquantique. L'observation du fond multiphonons donne directement le facteur de forme de la maille unitaire, qui permet de caracteriser le potentiel d'interaction. Comparaison avec des

Inelastic scattering on particles with inclusions

Journal of the Optical Society of America A, 2005
The investigation of particles with inclusions is of high interest in many parts of scientific research. Raman scattering is very good at yielding information on the internal composition of the particle. We use a geometrical-optics-based technique to determine the angle dependence of the inelastic scattering on particles with several spherical ...

Localization in elastic and inelastic scattering

Ultramicroscopy, 2003
The degree of information localization in elastic and inelastic scattering is examined in the context of imaging zone axis crystals in the aberration corrected STEM. We show that detector geometry is a critical factor in determining the localization, and compare a number of different geometries.

Inversion of Vibrationally Inelastic Scattering Data

Berichte der Bunsengesellschaft für physikalische Chemie, 1977
Methods are derived whereby vibrationally inelastic cross sections may be inverted to obtain a spherically symmetric effective potential (a rotational average of the complete potential) for atom/diatomic collisions. Classical and semi-classical methods are used to obtain inelastic opacity and deflection functions; these are further processed to give ...

On a Model Transport Equation with Inelastic Scattering

SIAM Journal on Applied Mathematics, 1998
Summary: In the frame of extended kinetic theory, a Lorentz-type model is proposed, which allows for inelastic scattering between a swarm of test particles and a background of heavy field particles. For the sake of simplicity, only two internal energy levels are considered for the background molecules.
