Inelastic and quasi-elastic neutron scattering. Application to soft-matter

EPJ Web of Conferences, 2018
Microscopic dynamical events control many of the physical processes at play in condensed matter: transport, magnetism, catalysis and even function of biological assemblies.

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.

Comparison of $K^+$ and $e^-$ Quasielastic Scattering [PDF]

, 1994
We formulate $K^+$-nucleus quasielastic scattering in a manner which closely parallels standard treatments of $e^-$-nucleus quasielastic scattering. For $K^+$ scattering, new responses involving scalar contributions appear in addition to the Coulomb (or ...

QENS investigation of proton confined motions in hydrated perfluorinated sulfonic membranes and self-assembled surfactants

EPJ Web of Conferences, 2015
We report on QuasiElastic Neutron Scattering (QENS) investigations of the dynamics of protons and water molecules confined in nanostructured perfluorinated sulfonic acid (PFSA) materials, namely a commercial Aquivion membrane and the perfluorooctane ...

Quasielastic electron- and neutrino-nucleus scattering in a continuum random phase approximation approach [PDF]

, 2014
We present a continuum random phase approximation approach to study electron- and neutrino-nucleus scattering cross sections, in the kinematic region where quasielastic scattering is the dominant process.

Understanding Heavy and Light Hole Transport Dynamics in Diamond Through Monte Carlo Simulations and Experiments

Advanced Theory and Simulations, Volume 9, Issue 2, February 2026.
Monte Carlo simulations of hole transport in diamond are presented, incorporating intraband acoustic and optical phonon scattering, as well as interband acoustic phonon scattering. Comparison with time‐of‐flight (ToF) measurements reveals distinct heavy‐ and light‐hole transport behaviors and population redistribution under applied electric fields ...

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 ...

Search for η-mesic 3He in non-mesonic final state [PDF]

EPJ Web of Conferences, 2019
The experiment on searching for η-mesic 3He nucleus was performed in May 2014 at COSY accelerator in Juelich by WASA-at-COSY Collaboration. The measurements were carried out using ramped beam technique which allows for the slow and continuous beam ...
