Molecular Mobility of a Polymer of Intrinsic Microporosity Revealed by Quasielastic Neutron Scattering

, 2020
Quasielastic neutron scattering by employing a combination of time-of-flight and backscattering techniques is carried out to explore the molecular mobility of a polymer of intrinsic microporosity (...

Quasielastic electron scattering

Physical Review C, 1974
Data and interpretation are presented for inelastic electron scattering in the quasielastic region from nine target nuclei ranging from lithium to lead at an incident energy of 500 MeV and a scattering angle of 60\ifmmode^\circ\else\textdegree\fi{}. The average kinetic and separation energies of nucleons in these nuclei are deduced.

Parity-violating quasielastic electron scattering

Nuclear Physics A, 1992
Abstract Parity-violating quasielastic electron scattering from nuclei is studied within the context of the relativistic Fermi gas model. Three issues are discussed: (i) the merits of such studies for obtaining new information about single-nucleon form factors, especially the roles played by the axial-vector and strangeness form factors, (ii) the ...

Quasielastic scattering in PrAl3

Physica B: Condensed Matter, 1997
Abstract Using the long-wavelength polarisation analysis neutron spectrometer (LONGPOL) fitted with time-of-flight analysis, the crystal field excitation spectrum of the rare earth trialuminide PrAl 3 was measured, and transitions of 4.5 and 3.7 meV were observed to take place between states of the Pr 3+ ion.

Dynamics of Hydride Ions in Metal Hydride-Reduced BaTiO3 Samples Investigated with Quasielastic Neutron Scattering

Journal of Physical Chemistry C, 2018
Perovskite-type oxyhydrides, BaTiO3–xHx, have been recently shown to exhibit hydride-ion (H–) conductivity at elevated temperatures, but the underlying mechanism of hydride-ion conduction and how it depends on temperature and oxygen vacancy concentration

Quasielastic electron scattering in quasiparticle approach

Physical Review C, 1992
A quasiparticle Hamiltonian, which includes the effects of Hartree-Fock and correlations, has been introduced through a parametrization of the radial shape of the effective mass ${\mathit{m}}^{\mathrm{*}}$(r)/m. Within this phenomenological quasiparticle approach the longitudinal and transverse response functions of quasielastic electron scatterings ...

Quasielastic Light Scattering from Diamond

Physical Review Letters, 1985
Strong quasielastic features have been found in light scattering from diamond in the frequency range 0 to \ifmmode\pm\else\textpm\fi{} 200 GHz and have been investigated as a function of wave-vector transfer ($Q$) and temperature ($T$). The evolution of a relatively narrow Lorentzian component (\ensuremath{\sim} 10 GHz) demonstrates for the first time ...
