Instrumentation for Small-Angle Scattering [PDF]
A review of small-angle X-ray (SAXS) and small-angle neutron (SANS) scattering instruments is given. The difference between long-slit and pinhole collimation and the influence of a broad band-pass monochromator are discussed with respect to the smearing of the measured scattering curves. The various components of SAXS setups are described: conventional

Small angle scattering and asphaltenes [PDF]
Petroleum is a mixture of organic material consisting of a series of molecules with increasing molecular weight but with decreasing carbon to hydrogen ratios. This monotonic trend leads to distinctive properties of each class, cut by solvents. Asphaltenes are a class soluble in toluene but not in heptane.

Small angle scattering of electrons
Nuclear Physics, 1960The small angle scattering of 615 keV electrons has been studied on N, A, Kr and Xe gases. It has been found that if the electron cloud of atoms is considered in Hartree representation, for angles ϑ < 1.5 × 10−3 radians, covered by our measurements, the differential cross sections for elastic and inelastic scattering are in agreement with the theory ...

On Small-Angle Critical Scattering
The Journal of Chemical Physics, 1962Recent theoretical studies of simplified models of cooperative assemblies of atoms or molecules suggest that the pair correlation function G(r) at the critical is not given by the Ornstein—Zernike (O.Z.) expression but that this relation becomes asymptotically valid for large distances r away from the critical.

Small-Angle Neutron Scattering
1997Small-angle neutron scattering (SANS) experiments from networks were initiated by Benoit and collaborators in the mid-1970s. Currently, SANS is an important major technique used in studying network structure and behavior. Its importance lies in its being a direct method with which observations may be made at the molecular-length scale without the need ...

Elastic scattering at small angles of protons
Nuclear Physics A, 1978Abstract Differential cross sections and asymmetries are obtained from elastic scattering, between 0° and 7°, of 36.2 MeV polarized protons by C, Al, Fe and Ni natural targets.

Small-angle neutron scattering
2000Abstract 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 ...

Limits of small angle scattering theory
Applied Optics, 1987On 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 ...
