Field-induced partial disorder in a Shastry-Sutherland lattice

open access: yesNature Communications, 2023
A 2-Q antiferromagnetic order of the ferromagnetic dimers was found below T N = 2.9 K in the Shastry-Sutherland lattice BaNd2ZnS5 by single crystal neutron diffraction.

The Scattering of Neutrons by Protons [PDF]

open access: yesProceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935
Abstract 1. The mass defects of the lightest nuclei, particularly the ratio between that of the diplon and the α-particle, make it very probable that the range of the interaction force between proton and neutron is very small, of the order of about 10-13 cm.

Towards spatially resolved magnetic small-angle scattering studies by polarized and polarization-analyzed neutron dark-field contrast imaging

open access: yesScientific Reports, 2021
In the past decade neutron dark-field contrast imaging has developed from a qualitative tool depicting microstructural inhomogeneities in bulk samples on a macroscopic scale of tens to hundreds of micrometers to a quantitative spatial resolved small ...

Neutron Total Scattering and Inelastic Neutron Scattering

open access: yesNihon Kessho Gakkaishi, 2004
Measurement of total scattering, which includes both the Bragg peaks and the diffuse scattering, can give information about the short-range structure of materials. This is quite useful for understanding the structure of liquid, glasses and amorphous materials.

Characterization of Crystallographic Structures Using Bragg-Edge Neutron Imaging at the Spallation Neutron Source

open access: yesJournal of Imaging, 2017
Over the past decade, wavelength-dependent neutron radiography, also known as Bragg-edge imaging, has been employed as a non-destructive bulk characterization method due to its sensitivity to coherent elastic neutron scattering that is associated with ...

Order-disorder in room-temperature ionic liquids probed via methyl quantum tunneling

open access: yesStructural Dynamics, 2021
Room-temperature ionic liquids are promising candidates for applications ranging from electrolytes for energy storage devices to lubricants for food and cellulose processing to compounds for pharmaceutics, biotransformation, and biopreservation.

Neutron scattering on nuclei

open access: yesNucleic Acids Research, 1979
Very small angle neutron scattering studies have been made on intact nuclei under a variety of solution conditions. Scattering maxima are observed at 30 to 40 nm and at 18 nm in most environments. Although the spacing, intensity and presence of the maximum near 40 nm varies considerably with environment the 18 nm is rather constant.

Quantum wake dynamics in Heisenberg antiferromagnetic chains

open access: yesNature Communications, 2022
It has long been suggested that the inverse Fourier transform of neutron scattering data gives access to space- and time-resolved spin-spin correlations. Scheie et al.
