Monte-Carlo ray-tracing studies of multiplexed prismatic graphite analyzers for the cold-neutron triple-axis spectrometer at the High Flux Isotope Reactor
Adit S. Desai, Travis J. Williams, Marcus Daum +4
A modern cold triple-axis spectrometer to study quantum condensed matter systems is planned for the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. Here, we desc…
Diffuse Inelastic Neutron Scattering from Anharmonic Vibrations in Cuprite
C. N. Saunders, V. V. Ladygin, D. S. Kim +5
Atomic vibrational dynamics in cuprite, Cu2O, was studied by inelastic neutron scattering and molecular dynamics (MD) simulations from 10 K to 900 K. Above 300 K, a diffuse inelast…
Zero-Point Motion of Liquid and Solid Hydrogen
T. R. Prisk, R. T. Azuah, D. L. Abernathy +5
We present an inelastic neutron scattering study of liquid and solid hydrogen carried out using the wide Angular Range Chopper Spectrometer at Oak Ridge National Laboratory. From t…
Spin wave Hamiltonian and anomalous scattering in NiPS
A. Scheie, Pyeongjae Park, J. W. Villanova +8
We report a comprehensive spin wave analysis of the semiconducting honeycomb van der Waal antiferromagnet NiPS. Using single crystal inelastic neutron scattering, we map out th…
