The measurement of self-diffusion coefficients in liquid metals with quasielastic neutron scattering

open access: yesEPJ Web of Conferences, 2015
Quasielastic incoherent neutron scattering (QENS) has proven to be a versatile tool to study self diffusion of atoms in liquid metals. Here it is shown, that coherent contributions to the signal in the small q limit appear as a flat and energy ...

Transverse Asymmetry A_T′ from the Quasielastic ^3He(e,e′) Process and the Neutron Magnetic Form Factor [PDF]

open access: yes, 2000
We have measured the transverse asymmetry A_T′ in ^3He(e,e′) quasielastic scattering in Hall A at Jefferson Laboratory with high precision for Q^2 values from 0.1 to 0.6 (GeV/c)^2.

Molecular spin-liquid state in spin-3/2 frustrated spinel HgCr$_2$O$_4$

open access: yes, 2011
A hexamer-type spin excitation seen in spinel chromates $A$Cr$_2$O$_4$ ($A$ = Mg, Zn, or Cd) is the representative spin-liquid-like state caused by geometrical frustration.

Very fast relaxation in polycarbonate glass

open access: yes, 2000
Low-frequency Raman and inelastic neutron scattering of amorphous bis-phenol A polycarbonate is measured at low temperature, and compared. The vibrational density of states and light-vibration coupling coefficient are determined.

Dynamics of Polyethersulfone Phenylene Rings:  A Quasielastic Neutron Scattering Study

open access: yesMacromolecules, 2005
By means of quasielastic neutron scattering, we have studied the hydrogen dynamics in glassy polyethersulfone, revealing the phenylene ring motions. The combination of a time-of-flight (TOF) and a backscattering spectrometer has allowed us to cover the microscopic and mesoscopic time scales (∼10-13−10-9 s) in a momentum transfer region well-suited to ...

Low-energy spin fluctuations in the non-Fermi-liquid compound YbRh2Si2

open access: yesScience and Technology of Advanced Materials, 2007
We report on inelastic neutron scattering experiments on YbRh2Si2 powder to study the low-energy spin dynamics at temperatures between T=0.8 and 22 K. The low-energy magnetic response is quasielastic.

Charged Current Neutrino Nucleus Interactions at Intermediate Energies

open access: yes, 2006
We have developed a model to describe the interactions of neutrinos with nucleons and nuclei, focusing on the region of the quasielastic and Delta(1232) peaks. We describe neutrino nucleon collisions with a fully relativistic formalism which incorporates

Modulation of Protein Dynamics by Glycerol in Water-Soluble Chlorophyll-Binding Protein (WSCP)

open access: yesCrystals
Proteins are inherently dynamic entities that rely on flexibility across multiple timescales to perform their biological functions. The surrounding environment plays a critical role in modulating protein dynamics by exerting plasticizing or stabilizing ...
