Small-angle neutron scattering

2009
Abstract The theory and practice of small-angle X-ray scattering (SAXS) dates back to the 1930s and is well described in the classic book of Guinier and Fournet (1955). Small-angle neutron scattering (SANS) came much later. It was not until the early 1970s, when position-sensitive detectors on cold neutron guides became available, that ...

Small-Angle X-Ray Scattering

1994
Small-angle X-ray scattering (SAXS) was discovered in 1938 by A. Guinier.(1) It is now a powerful method for characterizing catalysts (particle size, surface area) and disordered materials such as gels, sols, defective alloys, porous oxides or carbons, polymers.

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 Scattering Technique

2019
This chapter provides a basic overview of SAXS and SANS techniques, which includes definitions of the basic notions, description of main properties of x-rays and neutrons, a general mathematical background which describes the physical processes in a scattering experiment, and main procedures in experimental data analysis and extraction of structural ...

Biological Small Angle Scattering

2018
The technique of small angle solution scattering has been revolutionized in the last two decades. Exponential increases in computing power, parallel algorithm development, and the development of synchrotron, free-electron X-ray sources, and neutron sources, have combined to allow new classes of studies for biological specimens.

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 ...

Small Angle Scattering of Solutions

1979
The divergence of the synchrotron radiation received by the instruments at about 25m distance from the source is small and therefore ideally suited for small angle scattering experiments. A nearly point-like primary beam with respect to the half-width of the central peak of small angle scattering can be achieved without severe loss of intensity.

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

Instrumentation for Small-Angle Scattering

1995
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
