Small Angle Neutron Scattering

, 2016
Recent progress on materials for hydrogen storage have pointed out that kinetics and thermodynamics can be modified by nano-confinement of hydrides in porous scaffolds. The investigation of the structural features of these particular systems is challenging with conventional methods, for instance due to the lack of peaks in the diffraction pattern ...

Biological small-angle neutron scattering: recent results and development.

Acta Crystallographica Section D: Structural Biology, 2018
Small-angle neutron scattering (SANS) has increasingly been used by the structural biology community in recent years to obtain low-resolution information on solubilized biomacromolecular complexes in solution.

Investigations on small angle scattering with neutrons

Bulletin de la Société française de Minéralogie et de Cristallographie, 1967
L'application des neutrons très lents à la diffraction aux petits angles des réseaux déformés de longue période ou de grandes dimensions, offre des avantages par rapport à la diffraction des rayons X, proprement dite : — l'élimination de la double diffraction de Bragg.

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

2006
The use of small-angle neutron scattering (SANS) for the study of biological macromolecules is described. Topics covered in this chapter include: the theoretical basis of SANS; contrast variation; and the measurement of distances between chemically specified points in a macromolecule or macromolecular complex. Practical considerations are addressed and

Small-Angle Neutron Scattering

1997
Small-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 ...

An introduction to small-angle neutron scattering [PDF]

Journal of Applied Crystallography, 1988
Neutron and X-ray small-angle scattering provide, along with electron microscopy and diffraction, the principal techniques for the microscopic characterization of materials. Neutron, X-ray and electron beams each have quite different properties. In fact, each has unique advantages.

Neutron-proton scattering at small angles

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1955
Neutron-proton scattering has been measured from 6 to 61.5° c.m. for neutrons of effective energy 105 ± 3 and 137 + 5 MeV using a liquid hydrogen scatterer and a large neutron counter. The results confirm previous measurements and show a near symmetry around 90° at 105 MeV, and a fairly definite asymmetry at 137 MeV.

Small angle neutron scattering by opals

Physics and Chemistry of Minerals, 1997
Micro- and non-crystalline opals, chalcedony and flint show diffuse small angle neutron scattering (SANS). Precious opals give rise to two additional intensity maxima at very small scattering angles which are due to Bragg reflections from the closest packed non-crystalline silica spheres.

Small Angle Scattering of Neutrons

Physical Review, 1951
The differential and total scattering cross sections have been calculated for slow neutrons impinging on crystalline spheres whose radii are very much greater than the neutron wavelength. The results for the differential cross section show that when the difference, $\ensuremath{\rho}$, between the neutron phase shift in traversing the particle diameter
