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.

Self-diffusion in liquid gallium and hard sphere model

EPJ Web of Conferences, 2015
Incoherent and coherent components of quasielastic neutron scattering have been studied in the temperature range of T = 313 K – 793 K aiming to explore the applicability limits of the hard-sphere approach for the microscopic dynamics of liquid gallium ...

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.

Dynamic rotor mode in antiferromagnetic nanoparticles [PDF]

, 2015
We present experimental, numerical, and theoretical evidence for a new mode of antiferromagnetic dynamics in nanoparticles. Elastic neutron scattering experiments on 8 nm particles of hematite display a loss of diffraction intensity with temperature, the

Sample environment for simultaneous quasi‐elastic neutron scattering and Raman spectroscopy experiments demonstrated on polymer films under changing humidity and temperature

Journal of Applied Crystallography, Volume 58, Issue 6, Page 2026-2036, December 2025.
We present a sample environment for simultaneous quasi‐elastic neutron scattering and Raman spectroscopy experiments demonstrated on soft‐matter films under variable and controlled relative humidity and temperature.Understanding the dynamic and structural properties of matter across different timescales and length scales is essential for elucidating ...

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 ...

Inclusive quasielastic electron scattering on $^6$He: a probe of the halo structure [PDF]

, 2000
We investigate inclusive electron scattering reactions on two-neutron halo nuclei in the quasielastic region. Expressions for the cross section and structure functions are given assuming that the halo nucleus can be described as a three-body system ...

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.
