Superscaling and Neutral Current Quasielastic Neutrino-Nucleus Scattering beyond the Relativistic Fermi Gas Model [PDF]

Phys.Rev.C75:064617,2007, 2007
The superscaling analysis is extended to include quasielastic (QE) scattering via the weak neutral current of neutrinos and antineutrinos from nuclei. The scaling function obtained within the coherent density fluctuation model (used previously in calculations of QE inclusive electron and charge-changing (CC) neutrino scattering) is applied to neutral ...

Magnetic properties of the Ag-In-rare-earth 1/1 approximants

, 2011
We have performed magnetic susceptibility and neutron scattering measurements on polycrystalline Ag-In-RE (RE: rare-earth) 1/1 approximants. In the magnetic susceptibility measurements, for most of the RE elements, inverse susceptibility shows linear ...

Neutron lifetime measurements using gravitationally trapped ultracold neutrons

, 2009
Our experiment using gravitationally trapped ultracold neutrons (UCN) to measure the neutron lifetime is reviewed. Ultracold neutrons were trapped in a material bottle covered with perfluoropolyether.

The functional role of protein dynamics in photosynthetic reaction centers investigated by elastic and quasielastic neutron scattering

EPJ Web of Conferences, 2015
This short review summarizes our current knowledge about the functional relevance of protein dynamics in photosynthetic reaction centers. In the case of Photosystem II membrane fragments, elastic and quasielastic neutron scattering experiments reveal a ...

Dynamics of proteins with different molecular structures under solution condition

Scientific Reports, 2020
Incoherent quasielastic neutron scattering (iQENS) is a fascinating technique for investigating the internal dynamics of protein. However, low flux of neutron beam, low signal to noise ratio of QENS spectrometers and unavailability of well-established ...

Fast ionic mobility in cryolite studied by quasielastic neutron scattering [PDF]

Solid State Ionics, 2008
Abstract Quasielastic neutron scattering (QENS) has been used to study the relation between ionic mobility and conductivity at high temperature of the perovskite fluoride cryolite, Na3AlF6. Up to T = 880 °C the conductivity is dominated by jump diffusion of Na ions.

Lithium Ion Transport Environment by Molecular Vibrations in Ion‐Conducting Glasses

ENERGY &ENVIRONMENTAL MATERIALS, Volume 7, Issue 3, May 2024.
Li ions present in glasses can be classified by evaluating their valence oscillations via Bader analysis to topologically analyze the chemical bonds. It is found that three types of Li ions are present in Li3PS4 glass, and that the more mobile Li ions exhibit a characteristic correlation at relatively long distances of 4.0–5.0 Å.

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 ...

Unconventional spin fluctuations in the hexagonal antiferromagnet YMnO$_3$

, 2003
We used inelastic neutron scattering to show that well below its N\'{e}el temperature, $T_{\rm N}$, the two-dimensional (2D) XY nearly-triangular antiferromagnet YMnO$_{3}$ has a prominent {\it central peak} associated with 2D antiferromagnetic ...

Quasielastic Neutron Scattering Study on Polymer Nanocomposites

Journal of Physics: Conference Series, 2014
By using a quasielastic neutron scattering technique (disk-chopper-type spectrometer AMATERAS at J-PARC), we have investigated the microscopic dynamics of polybutadiene (PB) in which silica particles were embedded. The experimental results gave us both a damped vibration mode of PB and jumped diffusion motion of the segments.
