Quasielastic neutron scattering from two dimensional antiferromagnets at a finite temperature [PDF]

, 2010
We consider frequency dependence of the neutron scattering amplitude from a two-dimensional quantum antiferromagnet. It is well known that the long range order disappears at any finite temperature and hence the elastic neutron scattering Bragg peak is ...

Proton dynamics in phosphotungstic acid impregnated mesoporous silica proton exchange membrane materials

Green Energy & Environment, 2017
Phosphotungstic acid is an excellent proton conductor that can be incorporated into porous supports, and nanocomposite proton exchange membrane materials made from mesoporous silica impregnated with phosphotungstic acid have been suggested for use in ...

Effective Spectral Function for Quasielastic Scattering on Nuclei [PDF]

, 2014
Spectral functions that are used in neutrino event generators to model quasielastic (QE) scattering from nuclear targets include Fermi gas, Local Thomas Fermi gas (LTF), Bodek-Ritchie Fermi gas with high momentum tail, and the Benhar-Fantoni two ...

Quasielastic neutron scattering in soft matter

Current Opinion in Colloid & Interface Science, 2009
The general trend in soft matter is to study systems of increasing complexity which are more technologically and biologically relevant. This is facilitated by the capability of quasielastic neutron scattering (QENS) to selectively probe spatially resolved dynamical modes at a molecular level.

Study of the water dynamics near hydrophilic, nanostructured CuO surfaces by quasielastic and inelastic neutron scattering

AIP Advances, 2022
We have used quasielastic and inelastic neutron scattering to investigate the structure, dynamics, and phase transitions of water interacting with superhydrophilic CuO surfaces that not only possess a strong affinity for water but also a “grass-like ...

Barrier distribution from 28Si+154Sm quasielastic scattering: Coupling effects in the fusion process

EPJ Web of Conferences, 2016
Barrier distribution for the 28Si+154Sm system has been extracted from large angle quasielastic scattering measurement to investigate the role of various channel couplings on fusion dynamics.

Incoherent Quasielastic Neutron Scattering Study of Molecular dynamics of 4-n-cyano-4'-octylbiphenyl [PDF]

, 2008
We report incoherent quasielastic neutron scattering experiments on the thermotropic liquid crystal 4-n-cyano-4'-octylbiphenyl. The combination of time-of-flight and backscattering data allows analyzing the intermediate scattering function over about ...

Quasielastic neutron scattering experiment on water using TOFLAR (Time Of Flight and LARmor precession) technique at SNS

EPJ Web of Conferences, 2015
We present the results of the first TOFLAR (Time Of Flight and LARmor precession) experiment with a Larmor modulation device positioned after the sample. Using a setup based on the configuration of the SNS-NSE spectrometer (Spallation Neutron Source, USA)

Dynamic rotor mode in antiferromagnetic nanoparticles [PDF]

, 2015
We present experimental, numerical, and theoretical evidence for a new mode of antiferromagnetic dynamics in nanoparticles. Elastic neutron scattering experiments on 8 nm particles of hematite display a loss of diffraction intensity with temperature, the
