Limits of small angle scattering theory

Applied Optics, 1987
On decrit les resultats d'une comparaison de la theorie avec les simulations de Monte Carlo. En utilisant des profils d'attenuation identiques et des fonctions de diffusion volumiques, la validite de la theorie des petits angles peut etre directement ...

Small-angle neutron scattering in lysozyme solutions

Physical Review A, 1991
Small-angle neutron scattering has been performed on lysozyme solutions at different concentrations, both at the Intense Spallation Impulsed Source (ISIS), Rutherford-Appleton Laboratory) and at Orph\'ee (Laboratoire Leon Brillouin). The results show that, in addition to the large-scale structural properties revealed by light-scattering experiments ...

Small-angle neutron scattering

2000
Abstract Small-angle scattering (SAS) of X-rays or neutrons arises from scattering density fluctuations of the order 10—100 A. In biological studies, samples are usually solutions of macromolecules in this size range. Depending on the experimental conditions such as macromolecular concentration, for example, SAS provides information on ...

Small-Angle Scattering of Heterogeneous Catalysts

Journal of Applied Crystallography, 1997
A heterogeneously catalyzed reaction involves the adsorption of the reactants on the surface of the catalyst. Consequently, catalytic activity is usually strongly related to the microstructural features of the catalyst. Small-angle scattering (SAS) has been extensively used to study heterogeneous catalysts and it has been shown to provide useful ...

Small angle scattering of cell nuclei

European Biophysics Journal, 1986
Neutron and X-ray small angle scattering techniques have been applied to study chromatin structure inside different types of cell nuclei. Scattering from genetically inactive chicken erythrocyte nuclei exhibits a maximum at Q = 0.1-0.15 nm-1 which cannot be observed by studying isolated chromatin derived from the same kind of cells.

Kinematics of small angle scattering

The Journal of Chemical Physics, 1974
In beam-recoil measurements of the scattering of molecules by electrons or photons, deflected molecules are observed at very small angles, comparable to the angular divergences of the observed and crossing beams. A kinematic analysis is presented that explicitly includes the effects of these divergences.

Small angle scattering of electrons

Physics Letters A, 1973
Abstract The small angle scattering of low energy electrons has been studied. It has been shown that the cross-sections obtained using the Born's first approximation, corrected for screening effects should be used to study the small angle scattering of low energy electrons.
