Study of neutron fundamental properties in the perfect crystal optics and diffraction [PDF]

EPJ Web of Conferences, 2019
Review of the new crystal-diffraction methods to study fundamental neutron properties and interactions is presented. Features of neutron optics in the crystal without a center of symmetry is discussed as well as the first experimental results and ...

Measurement of strain evolution in overloaded roller bearings using time-of-flight neutron diffraction

Materials & Design, 2020
Neutron diffraction is an established method for non-destructively characterising residual stress or observing in situ strain during external stimuli. Neutron based stroboscopic techniques have previously been introduced for measuring strains undergoing ...

Recent Progress of Residual Stress Distribution and Structural Evolution in Materials and Components by Neutron Diffraction Measurement at RSND

Quantum Beam Science, 2018
Neutron diffraction is an effective and nondestructive method to investigate inner structure and stress distribution inside bulk materials and components. Compared with X-ray diffraction, neutron diffraction allows a relatively high penetration depth and

Investigation of Structural and Thermal Evolution in Novel Layered Perovskite NdSrMn2O5+δ via Neutron Powder Diffraction and Thermogravimetric Analysis

International Journal of Chemical Engineering, 2020
Neutron diffraction is one of the best methods for structural analysis of a complex, layered perovskite material with low symmetry by accurately detecting the oxygen positions through octahedral tilting.

Diffraction of Neutrons by Imperfect Gases [PDF]

Physical Review, 1958
The theory of cluster expansions is studied by a new method. A general procedure for obtaining the thermal average of a many-body function as a series in powers of density is derived. A recipe based on the Daker-Hausdorff theorem for reducing quantum thermal averages to their classical analogs is also described.

Neutron diffraction study of the Cr84.7Re15.3 alloy

AIP Advances, 2021
Measurements of the temperature dependence of electrical resistance (R) and neutron powder diffraction (NPD) of a Cr84.7Re15.3 alloy is reported. The magnetism originates from the formation of a spin-density-wave (SDW) as a result of nesting between the ...

Magnetic ordering in Gd5Ir2Bi and Gd5Ir2Sb

AIP Advances, 2016
155Gd Mössbauer spectroscopy and neutron powder diffraction have been used to study magnetic ordering in Gd5Ir2Bi and Gd5Ir2Sb. Despite the hyperfine fields (Bhf) at the two Gd sites differing by more than a factor of two for both compounds, the moments ...
