Quasielastic Neutron Scattering Study on Thermal Gelation in Aqueous Solution of Agarose [PDF]

Gels, 2023
The dynamics of water and agarose molecules in an agarose aqueous solution has been studied by means of quasielastic neutron scattering (QENS). The dynamic structure factor S (Q,E) of the agarose aqueous solution was fitted well to the sum of the Lorentz

SHERPA: A Spectrometer with High Energy Resolution and Polarisation Analysis [PDF]

EPJ Web of Conferences, 2022
SHERPA is a proposed quasielastic neutron spectrometer with polarisation analysis, intended to replace the ageing Iris instrument at the ISIS neutron and muon source. In this paper we present a concept of the instrument along with Monte-Carlo simulations

The SuSA Model for Neutrino Oscillation Experiments: From Quasielastic Scattering to the Resonance Region

Universe, 2021
High-precision studies of Beyond-Standard-Model physics through accelerator-based neutrino oscillation experiments require a very accurate description of neutrino–nucleus cross-sections in a broad energy region, going from quasielastic scattering up to ...

Dynamics of water within Cu-loaded zeolites: A quasielastic neutron scattering study

Catalysis Communications, 2022
Quasielastic Neutron Scattering (QENS) was employed in order to probe the dynamics of water confined within copper-loaded MOR, MFI and CHA zeolite frameworks in the temperature range 100–300 K.

Impact of composition on the crystal texture and on the dynamics of P(THF-co-ECH) copolymers [PDF]

EPJ Web of Conferences, 2022
We present a combined study by quasielastic neutron scattering (QENS), differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS) on poly(tetrahydrofuran-co-epichlorohydrin) copolymers, to see how their composition can be used to tune

Scattering of the halo nucleus 11Be from a lead target at 3.5 times the Coulomb barrier energy

Physics Letters B, 2020
Angular distributions of quasielastic scattering and breakup of the neutron-rich halo nucleus 11Be on a 208Pb target at an incident energy of 140 MeV (about 3.5 times the Coulomb barrier) were measured at HIRFL-RIBLL.

Dynamics–Function Correlation in Photosystem II: Molecular Dynamics in Solution

Crystals, 2023
A detailed comprehension of protein function requires information on the spatial structure of the protein, which is often gathered from X-ray crystallography.

Identifying the Spin-Incoherent Contribution to Quasielastic Neutron Scattering with a Cold Triple-Axis Spectrometer

Quantum Beam Science, 2023
Polarisation analysis for neutron scattering experiments is a powerful tool suitable for a wide variety of studies, including soft-matter samples which have no bulk magnetic behaviour and/or a significant hydrogen content.

Revisiting the modeling of quasielastic neutron scattering from bulk water [PDF]

EPJ Web of Conferences, 2022
Quasi-elastic neutron scattering (QENS) from bulk-water at 300 K, measured on the IRIS backscattering neutron spectrometer (ISIS, UK), is interpreted using the jump diffusion model (JDM), a “minimalistic” multi-timescale relaxation model (MRM) and ...

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 ...
