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

Ядерна фізика та енергетика, 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-

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 ...

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 ...

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 ...

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.

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.

IR Spectroscopic Studies on Water Confined in an Isoreticular MOF Series–Influence of the Metal and Linker Functionality

Advanced Materials Interfaces, Volume 12, Issue 10, May 19, 2025.
Mono‐ and bimetallic isoreticular MOF‐74 analogs with different ratios of Mg2+ and Ni2+ and linkers of different sizes and functionalities are synthesized and loaded with water. With the help of IR spectroscopy, semiquantitative conclusions are drawn regarding the prevalence of differently ordered water species in dependence on the confinement and ...

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.

Hydride Migration within RhH2Ag19 Superatom: A Combined Neutron Diffraction and DFT Analysis

Small, Volume 21, Issue 18, May 5, 2025.
By modifying the crystallization conditions, the migration pathway of interstitial hydrides is visualized for the first time and analyzed through neutron diffraction experiments combined with DFT calculations. The computational results reveal an approximate migration energy barrier of 4.2 kcal mol−1, providing a reasonable explanation for the ...
