Handed Magnon Propagation in Easy‐Axis Antiferromagnetic α‐Fe2O3

open access: yesAdvanced Materials, EarlyView.
Coherent excitation and detection of handed magnons are achieved in the easy‐axis antiferromagnet α‐Fe2O3. An external magnetic field lifts the degeneracy between left‐ and right‐handed magnons without affecting their propagation velocity. The Dzyaloshinskii–Moriya interaction and anisotropy modulate their amplitude and damping, enabling intrinsic ...

Differential Cross Sections for Neutron Elastic and Inelastic Scattering on 23Na

open access: yesEPJ Web of Conferences, 2014
Measurements of neutron elastic and inelastic scattering from 23Na have been performed for sixteen incident neutron energies above 1.5 MeV with the 7-MV University of Kentucky Accelerator using the 3H(p,n) reaction as the neutron source.

Quantum Monte Carlo Calculations of Pion Scattering from Li

open access: yes, 2000
We show that the neutron and proton transition densities predicted by recent quantum Monte Carlo calculations for A=6,7 nuclei are consistent with pion scattering from 6Li and 7Li at energies near the Delta resonance.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Neutron and X-ray Scattering Studies of the Lightly-Doped Spin-Peierls System Cu(1-x)Cd(x)GeO3

open access: yes, 2007
Single crystals of the lightly-doped spin-Peierls system Cu(1-x)Cd(x)GeO3 have been studied using bulk susceptibility, x-ray diffraction, and inelastic neutron scattering techniques.

Spin liquid correlations in Nd-langasite anisotropic Kagom\'e antiferromagnet [PDF]

open access: yes, 2006
Dynamical magnetic correlations in the geometrically frustrated Nd$\_3$Ga$\_5$SiO$\_{14}$ compound were probed by inelastic neutron scattering on a single crystal.

Defect Engineering in Large‐Scale CVD‐Grown Hexagonal Boron Nitride: Formation, Spectroscopy, and Spin Relaxation Dynamics

open access: yesSmall, EarlyView.
The controlled formation of defects in large‐area CVD‐grown hBN using various irradiation methods is demonstrated. Defect type and properties depend on particle type (He+, Ne+, Ar+, neutrons, and electrons), substrate effects, and film thickness.

A new thermography using inelastic scattering analysis of wavelength-resolved neutron transmission imaging

open access: yesScientific Reports, 2023
Thermography using energy-dependent neutron transmission imaging can non-invasively and non-destructively visualize a real-space distribution of interior temperatures of a material in a container.

Dual-mode operation of a neutron source, a concept [PDF]

open access: yes, 1969
Pulsed neutron source operates in conjunction with a photomultiplier tube coupled to a gamma ray scintillation crystal. This allows measurements of gamma radiation from both inelastic scattering and thermal neutron capture in a single ...

Magnetic‐lens‐generated polarized neutron beam with enhanced intensity and Q resolution for small‐angle neutron scattering

open access: yesJournal of Applied Crystallography, EarlyView.
While maintaining or even improving Q resolution, a long array of short‐focal‐length magnetic lenses, with zero transmission loss and no diffuse scattering, successfully polarized and enhanced the intensity of neutron beams for small‐angle neutron scattering at momentum transfer Q > 0.1 nm−1.We installed a 30 mm‐bore 3.2 m‐long magnetic lens in the ...
