Hyperfine interaction and electronic spin fluctuation study on Sr$_{2-x}$La$_x$FeCoO$_6$ (x = 0, 1, 2) by high-resolution back-scattering neutron spectroscopy

, 2018
The study of hyperfine interaction by high-resolution inelastic neutron scattering is not very well known compared to the other competing techniques viz. NMR, M\"ossbauer, PACS etc. Also the study is limited mostly to magnetically ordered systems.

Diffusion in dense supercritical methane from quasi-elastic neutron scattering measurements

Nature Communications, 2021
Methane is abundant in the Universe, is an important energy carrier and a model system for fundamental studies. Here, the authors measure the self-diffusion coefficient of supercritical methane at ambient temperature up to the freezing pressure, and find

Probing the dynamics of biological matter by elastic, quasi-elastic, and inelastic neutron scattering [PDF]

EPJ Web of Conferences, 2020
The so-called function-structure-dynamics paradigm established that a close relationship links the way biological molecules work (function), their 3-dimensional organization (structure) and the changes of this organization in time (dynamics), which ...

Glass Transition in the Polaron Dynamics of CMR Manganites

, 2002
Neutron scattering measurements on a bilayer manganite near optimal doping show that the short-range polarons correlations are completely dynamic at high T, but then freeze upon cooling to a temperature T* 310 K.

Neutral-current neutrino-nucleus quasielastic scattering

, 2004
A relativistic distorted-wave impulse-approximation model to quasielastic neutral-current neutrino-nucleus scattering is developed, using the relativistic mean field theory for the bound state and taking into account the final state interaction in the ...

Quasi- and inelastic neutron scattering to investigate the molecular dynamics of discotic molecules in the bulk

EPJ Web of Conferences, 2015
In- and quasielastic neutron scattering is employed to investigate both the vibrational density of states and the molecular dynamics of two homologous discotic liquid crystals (DLC) with different length of the alkyl side chain based on a triphenylene ...

Rotation of complex ions with ninefold hydrogen coordination studied by quasielastic neutron scattering and first-principles molecular dynamics calculations

Physical Review Research, 2022
Quasielastic neutron scattering (QENS) and neutron powder diffraction of the complex transition metal hydrides Li_{5}MoH_{11} and Li_{6}NbH_{11} were measured in a temperature range of 10–300 K to study their structures and dynamics, especially the ...

Neutrino quasielastic interaction and nuclear dynamics

, 2011
We investigate the double differential neutrino-carbon quasielastic cross sections as measured by the MiniBooNE experiment. Our present treatment incorporates relativistic corrections in the nuclear response functions and includes the multinucleon ...
