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 ...

Translational Dynamics of Imidazolium-Based Ionic Liquids in Acetonitrile Solutions

Liquids, 2023
The dynamics of pure ionic liquids and solutions with acetonitrile have been investigated through quasielastic neutron scattering (QENS). The translational diffusive motion of the 1-butyl-3-methyl-imidazolium cation was revealed as a function of ...

Magnetic fluctuations in frustrated Laves hydrides R(Mn_{1-x}Al_{x})_{2}H_{y}

, 2003
By neutron scattering, we have studied the spin correlations and spin fluctuations in frustrated Laves hydrides, where magnetic disorder sets in the topologically frustrated Mn lattice. Below the transition towards short range magnetic order, static spin

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 ...

Spin asymmetries in quasielastic charged current neutrino-nucleon scattering [PDF]

Phys. Rev. D 101, 073002 (2020), 2019
The work concerns the quasielastic charged current neutrino-neutron and antineutrino-proton interactions. Single, double, and triple spin asymmetries are computed and analyzed. The spin asymmetries are sensitive to the axial form factor of the nucleon.

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 ...

Precise quasielastic neutrino/nucleon cross section [PDF]

Phys.Lett.B564:42-54,2003, 2003
Quasielastic antineutrino/proton and neutrino/neutron scatterings can be well approximated by simple formulae, valid around MeV or GeV energies. We obtain a single expression valid in the whole range, and discuss its relevance for studies of supernova neutrinos, which reach intermediate energies.

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

Advanced Materials Interfaces, EarlyView.
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 ...

Quasielastic production of polarized hyperons in antineutrino--nucleon reactions [PDF]

Phys. Rev. D 94, 114031 (2016), 2016
We have studied the differential cross section as well as the longitudinal and perpendicular components of polarization of final hyperon($\Lambda$,$\Sigma$) produced in the antineutrino induced quasielastic charged current reactions on nucleon and nuclear targets.
