Comparison of $K^+$ and $e^-$ Quasielastic Scattering [PDF]

, 1994
We formulate $K^+$-nucleus quasielastic scattering in a manner which closely parallels standard treatments of $e^-$-nucleus quasielastic scattering. For $K^+$ scattering, new responses involving scalar contributions appear in addition to the Coulomb (or longitudinal) and transverse $(e,e')$ responses which are of vector character.

Multipeak quasielastic light scattering and high-frequency electronic excitations in honeycomb Li$_2$RuO$_3$ [PDF]

, 2020
We measured the temperature dependence of low-frequency Raman spectra in Li$_2$RuO$_3$, and observed multipeak quasielastic scattering in the Ru honeycomb polarizations below and above the magnetostructural transition temperature. We attribute this scattering to the fluctuations of the energy density in the spin system.

CO2 Uptake and Stability Enhancement in Vinyltrimethoxysilane‐Treated SBA‐15 Solid Amine‐Based Sorbents

Small, Volume 20, Issue 46, November 14, 2024.
A new surface treatment using vinyltrimethoxysilane on poly(ethyleneimine) (PEI)‐loaded B‐doped mesoporous silica is reported, which increases the activity of nitrogen sorption sites for CO2 capture under direct air capture and point‐source capture conditions.

Electron- and neutrino-nucleus scattering from the quasielastic to the resonance region [PDF]

Phys.Rev.C79:034601,2009, 2008
We present a model for electron- and neutrino-scattering off nucleons and nuclei focussing on the quasielastic and resonance region. The lepton-nucleon reaction is described within a relativistic formalism that includes, besides quasielastic scattering, the excitation of 13 N* and Delta resonances and a non-resonant single-pion background.

Insight into the reaction dynamics of proton drip-line nuclear system 17F+58Ni at near-barrier energies

Physics Letters B, 2021
The mechanism of reactions with weakly-bound proton-rich nuclei at energies near the Coulomb barrier is a long-standing open question owing to the paucity of experimental data. In this study, a complete kinematics measurement was performed for the proton

Quasielastic scattering with the Relativistic Green's Function approach [PDF]

arXiv, 2013
A relativistic model for quasielastic (QE) lepton-nucleus scattering is presented. The effects of final-state interactions (FSI) between the ejected nucleon and the residual nucleus are described in the relativistic Green's function (RGF) model where FSI are consistently described with exclusive scattering using a complex optical potential.

Coherent quasielastic neutron scattering and correlations between rotational jumps of molecules on a periodic lattice [PDF]

, 2002
We previously derived a theorem about the {\em coherent} quasielastic neutron-scattering signal from a $d$-dimensional lattice of $N$ molecules that are undergoing rotational jump diffusion (around an $n$-fold axis), assuming that there are no correlations between the molecules.

Mode‐Selective Spin–Phonon Coupling in van der Waals Antiferromagnets

Advanced Physics Research, Volume 3, Issue 6, June 2024.
Spin–phonon coupling is one of the most important interactions correlating charge, spin and lattice vibrations. Understanding and controlling this coupling is important for next‐generation applications. Here, spin–phonon coupling in layered anti‐ferromagnetic MPS3 (M = Ni, Fe, Co, and Mn) compounds is measured using temperature‐dependent resonant Raman

Diffusion in dense supercritical methane from quasi-elastic neutron scattering measurements

Nature Communications, 2021
Methane is abundant in the Universe, is an important energy carrier and a model system for fundamental studies. Here, the authors measure the self-diffusion coefficient of supercritical methane at ambient temperature up to the freezing pressure, and find

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.
