Precision Measurement of the n-3He Incoherent Scattering Length Using Neutron Interferometry [PDF]

, 2009
We report the first measurement of the low-energy neutron-$^3$He incoherent scattering length using neutron interferometry: $b_i' = (-2.512\pm 0.012{statistical}\pm0.014{systematic})$ fm. This is in good agreement with a recent calculation using the AV18+

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

Scientific 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 ...

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

Structural 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 Total Scattering and Inelastic Neutron Scattering

Nihon 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

Journal 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 ...

Quantum wake dynamics in Heisenberg antiferromagnetic chains

Nature 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.

Dipolar spin-waves and tunable band gap at the Dirac points in the 2D magnet ErBr3

Communications Physics, 2022
Magnonic devices, based on the physics of spin-waves, are a potential alternative to process and store information that consume less energy and van der Waals crystals are candidate materials for such applications.

Detection of Neutron Scattering from Phase IV of Ce0.7La0.3B6: A Confirmation of the Octupole Order [PDF]

, 2007
We have performed a single crystal neutron scattering experiment on Ce0.7La0.3B6 to investigate the order parameter of phase IV microscopically. Below the phase transition temperature 1.5 K of phase IV, weak but distinct superlattice reflections at the ...
