Quasielastic Scattering of Thermal Neutrons by CH3OH and CH3SH [PDF]

The Journal of Chemical Physics, 1969
We report measurements of the line broadening of thermal neutrons quasielastically scattered from room temperature methyl alcohol and methyl mercaptan in the liquid phase. The linewidths for CH3SH are found to be approximately twice those of CH3OH. This is interpreted to be additional evidence of the relative freedom of molecular motions and lack of ...

Study of the water dynamics near hydrophilic, nanostructured CuO surfaces by quasielastic and inelastic neutron scattering [PDF]

AIP Advances, 2022
We have used quasielastic and inelastic neutron scattering to investigate the structure, dynamics, and phase transitions of water interacting with superhydrophilic CuO surfaces that not only possess a strong affinity for water but also a “grass-like ...

Quasielastic magnetic scattering of neutrons at the systems with heavy fermions [PDF]

Journal of Experimental and Theoretical Physics Letters, 1998
The theory of the quasielastic magnetic scattering of neutrons at the spin liquid with RVB (resonance valence bonds) correlations is presented. Calculations demonstrate that the dependence of the scattering cross section on the energy transfer reproduces experimental shape of quasielastic peak in heavy fermion systems. It is shown that Fermi statistics

Dynamical Behavior of Human α-Synuclein Studied by Quasielastic Neutron Scattering. [PDF]

PLoS ONE, 2016
α-synuclein (αSyn) is a protein consisting of 140 amino acid residues and is abundant in the presynaptic nerve terminals in the brain. Although its precise function is unknown, the filamentous aggregates (amyloid fibrils) of αSyn have been shown to be ...

Dynamics of water within Cu-loaded zeolites: A quasielastic neutron scattering study

Catalysis Communications, 2022
Quasielastic Neutron Scattering (QENS) was employed in order to probe the dynamics of water confined within copper-loaded MOR, MFI and CHA zeolite frameworks in the temperature range 100–300 K.

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.

Electron scattering on two-neutron halo nuclei: The case of $^6$He [PDF]

Nucl.Phys. A650 (1999) 387-417, 1999
The formalism to describe electron scattering reactions on two-neutron halo nuclei is developed. The halo nucleus is described as a three-body system (core+n+n), and the wave function is obtained by solving the Faddeev equations in coordinate space. We discuss elastic and quasielastic scattering using the impulse approximation to describe the reaction ...

Neutron scattering study of magnetic ordering and excitations in the ternary rare-earth diborocarbide Ce^{11}B_2C_2 [PDF]

, 2007
Neutron scattering experiments have been performed on the ternary rare-earth diborocarbide Ce$^{11}$B$_2$C$_2$. The powder diffraction experiment confirms formation of a long-range magnetic order at $T_{\rm N} = 7.3$ K, where a sinusoidally modulated structure is realized with the modulation vector ${\bm q} = [0.167(3), 0.167(3), 0.114(3)]$.

Hydration of ds-DNA and ss-DNA by Neutron Quasielastic Scattering [PDF]

Biophysical Journal, 2004
Quasielastic neutron scattering measurements were performed in hydrated samples of ds-DNA and ss-DNA. The samples were hydrated in a high relative humidity atmosphere, and their final water content was 0.559 g H(2)O/g ds-DNA and 0.434 g H(2)O/g ss-DNA.
