Quasielastic scattering of slow-neutron in water-alcohol solutions [PDF]

Âderna Fìzika ta Energetika, 2010
Research of molecules dynamics of solutions “water - propyl alcohol” of different concentration at the temperature 281 K is conducted by the method of slow-neutron quasi-elastic scattering. There were experimentally exposed the feature of effective self-

Sub-barrier backward quasielastic scattering: A probe of the hexadecapole deformation

EPJ Web of Conferences, 2016
The quasielastic scattering excitation functions for 16O + 152Sm,170Er and 174Yb were measured with high precision at a backward angle with small energy intervals at energies near the Coulomb barriers.

Probing the Structure and Dynamics of the [NH4]M(HCO2)3 Ferroelectric Phases: Dielectric Relaxation through Orientational Disorder†

Chinese Journal of Chemistry, Volume 43, Issue 10, Page 1190-1198, 15 May 2025.
The polar [NH4]M(HCO2)3 frameworks exhibit dielectric relaxation due to orientational disorder of the NH4, as identified by a multi‐technique examination of their structure and dynamics. Comprehensive Summary Neutron diffraction studies of the low‐temperature relaxor ferroelectric phases of [NH4]M(HCO2)3, where M = Mn2+ and Zn2+, show that a third of ...

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 ...

Unveiling Electron‐Phonon and Electron‐Magnon Interactions in the Weak Itinerant Ferromagnet LaCo2P2

Advanced Physics Research, Volume 4, Issue 4, April 2025.
Electron‐boson interactions in the weak itinerant ferromagnet LaCo2P2 are investigated, addressing both surface and bulk properties. The intricate renormalization of electronic states due to electron‐phonon and electron‐magnon interactions is examined, highlighting their distinct impacts on the electronic structure.

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 ...

Superscaling analysis of quasielastic electron scattering with relativistic effective mass [PDF]

Phys. Rev. D 95, 076009 (2017), 2017
We provide a parametrization of a new phenomenological scaling function obtained from a chi-square fit to a selected set of (e,e') cross section data expanding a band centered around the quasielastic peak. We start from a re-analysis of quasielastic electron scattering from nuclear matter within the relativistic mean field model.

How sensitive are protein hydration shells to electrolyte concentration and protein composition?

Protein Science, Volume 34, Issue 1, January 2025.
Abstract Proteins of obligate halophilic organisms have an unusually high number of acidic amino acids, thought to enable them to function in multimolar KCl environments. Clarifying the molecular scale mechanisms by which this occurs is relevant for biotechnology, to enable enzymatic synthesis of economically important small molecules in salty ...

Exclusive J/Ψ,ρ,ϕ and γ production at HERA and LHC within dipole models

EPJ Web of Conferences, 2018
We describe exclusive J/ψ,ρ,Φ and γ production at HERA and calculate cross sections and transverse momentum distributions for the incoherent diffractive production of vector mesons J/ψ and γ on heavy nuclei.

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 ...
