Small angle neutron scattering invar alloys
Journal of Magnetism and Magnetic Materials, 1978Abstract Some results of low angle neutron scattering on a 70-30 single crystal Fe 60 Ni alloy are presented showing the existence of chemical small clusters associated with a magnetization inhomegeneity. On the hand, 70-30 and 65-35 FeNi single crystal samples, have been also measured after 2-MeV electrons irradiation.

Small angle neutron scattering by opals
Physics and Chemistry of Minerals, 1997Micro- 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 Thermal Neutrons
Physical Review, 1950Experiments on the small angle scattering of thermal neutrons by powders are compared with theory. The available theories, which closely resemble those for small angle scattering of x-rays, are found to give a satisfactory account of the results. In general, the neutrons are scattered into a Gaussian distribution in angle whose width is directly ...

Small angle neutron scattering from TiBe1.5Cu0.5
Journal of Magnetism and Magnetic Materials, 1992Abstract Metals on the verge of and just in the weakly magnetic state offer a unique test ground for current theories of itinerant magnetism. TiBe 1.5 Cu 0.5 becomes ferromagnetic below 27 K with a low temperature moment of 0.07μ B per average atom.

Neutron-proton scattering at small angles
Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1955Neutron-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 and neutron reflectometry
1993Diffraction methods, interpreted loosely, could be applied to the techniques of wide-angle X-ray scattering, small-angle X-ray scattering, electron diffraction, small-angle neutron scattering, small-angle light scattering and reflectometry. Each of the above techniques is defined by the size range explored and the property that causes the scattering ...

Small Angle Neutron Scattering Complementing Neutron Radiography
1983In neutron radiography inhomogeneities of sizes down to a few micrometers are detectable by an imaging technique. In small angle neutron scattering (SANS) experiments inhomogeneities in the A range up to 1000 A diameter are observed by neutron scattering.

Small angle neutron scattering from steels
Colloid and Polymer Science, 1981By small angle neutron scattering from steels valuable quantitative parameters of the microstructure can be obtained in a non-destructive way. Various features of this method are discussed. Microstructural results are presented which were obtained from neutron scattering experiments with neutron-irradiated pressure vessel steel, with a creep-tested ...
