Spin dynamics of strongly-doped La_{1-x}Sr_xMnO_3

, 1997
Cold neutron triple-axis measurements have been used to investigate the nature of the long-wavelength spin dynamics in strongly-doped La$_{1-x}$Sr$_{x}$MnO$_3$ single crystals with $x$=0.2 and 0.3. Both systems behave like isotropic ferromagnets at low T,

Neutrino Quasielastic Scattering on Nuclear Targets: Parametrizing Transverse Enhancement (Meson Exchange Currents) [PDF]

, 2011
We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum transfer ($Q^2$) in terms of a correction to the ...

Performance of the neutron polarimeter NPOL3 for high resolution measurements [PDF]

, 2005
We describe the neutron polarimeter NPOL3 for the measurement of polarization transfer observables $D_{ij}$ with a typical high resolution of $\sim$300 keV at $T_n$ $\simeq$ 200 MeV. The NPOL3 system consists of three planes of neutron detectors. The

Radiative tail from the quasielastic peak in deep inelastic scattering of polarized leptons off polarized He-3 [PDF]

, 2000
The contribution of the radiative tail from the quasielastic peak to low order radiative correction to deep inelastic scattering of polarized leptons by polarized $^3$He was calculated within the sum rules formalism and $y$-scaling hypothesis.

Magnetic Bragg peak enhancement under ultrasound injection

Physical Review Research, 2022
Ultrasound injection effect on a magnetic Bragg peak of yttrium iron garnet has been studied by quasielastic neutron scattering. The magnetic Bragg peak is vastly enhanced with decreasing temperature.

4f-spin dynamics in La(2-x-y)Sr(x)Nd(y)CuO(4)

, 1999
We have performed inelastic magnetic neutron scattering experiments on La(2-x-y)Sr(x)Nd(y)CuO(4) in order to study the Nd 4f-spin dynamics at low energies.

A note on quasielastic neutron scattering

Journal de Physique I, 1994
We present a theorem that in coherent quasielastic neutron scattering on a confined and limited system of identical particles only the configuration-configuration correlations have to be examined without any hindsight on the distribution of the particles inside the configuration.

Low‐Frequency Raman Spectroscopy of Polymers

Macromolecular Chemistry and Physics, Volume 226, Issue 15, August 4, 2025.
Recent advances have made low‐frequency Raman spectroscopy accessible to the wider scientific community. This review discusses how low‐frequency Raman is particularly useful for researchers investigating polymers because the technique can help determine both the local and long‐range structure of materials, their thermodynamic properties, and their ...

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

, 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 ...
