Small-angle neutron scattering
2009Abstract 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 neutron scattering in lysozyme solutions
Physical Review A, 1991Small-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 ...

Multiple Small-Angle Neutron Scattering
Journal of Neutron Research, 1999Over the past decade, a multiple small-angle neutron scattering (MSANS) formalism has been developed to enable researchers to derive microstructural parameters from multiply-scattered small-angle neutron data. The MSANS formalism is particularly useful in ceramic science and materials research because it is applicable to samples that are thicker (>

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 ...

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 ...

Phase-sensitive small-angle neutron scattering
Journal of Applied Crystallography, 2014A method is described for determining the neutron scattering length density distribution of a molecular-scale object directly from phase-sensitive small-angle neutron scattering (SANS). The structure factor amplitude is obtained through the use of a reference structure for a collection of randomly oriented, identical objects in the dilute solution ...

Small Angle Scattering of Neutrons
Physical Review, 1951The 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

Small angle neutron scattering from polymer networks
The Journal of Chemical Physics, 1979The small angle neutron scattering of labeled chains in a polymer network has been calculated for several possible models of the network. Cases of isotropic and anisotropic deformation are considered. The influence of entanglements is examined. Results are presented in graphical form, and low angle and high angle limiting behavior is treated.

Small Angle Neutron Scattering Using Sans2d
Neutron News, 2011The Loq small angle neutron scattering (SANS) instrument at ISIS target station one (TS1) has proved an extremely popular and immensely productive SANS facility over the last 20 years. Loq is routinely operated with a 25 Hz disc chopper removing alternate neutron pulses from the 50 Hz source to provide a usable wavelength range of 2.2 to 10 A ...

Small-angle neutron-scattering facility
Physics Today, 1978A user-oriented facility for small-angle neutron scattering is to be built at Oak Ridge National Laboratory at a cost of $1.4 million spread over three years. Funds come from NSF under an interagency agreement with the Department of Energy.
