Structure-Dependent Doppler Broadening Using a Generalized Thermal Scattering Law

open access: yesJournal of Nuclear Engineering, 2021
The thermal scattering law (TSL), i.e., S(α,β), represents the momentum and energy exchange phase space for a material. The incoherent and coherent components of the TSL correlate an atom’s trajectory with itself and/or with other atoms in the lattice ...

Influence of electron-phonon interaction on wannier–stark effect in macroporous silicon structures with SiO2 nanocoatings

open access: yesХімія, фізика та технологія поверхні, 2014
We investigated the contribution of electron-phonon interaction to the broadening parameter of the Wannier–Stark ladders in oxidized macroporous silicon structures with different concentration of Si–O–Si states (TO and LO phonons).

Application the Ion Beam Sputtering Deposition Technique for the Development of Spin-Wave Structures on Ferroelectric Substrates

open access: yesCeramics, 2023
The microwave properties of structures in the form of the 2 μm iron-yttrium garnet (YIG) films, grown by the ion beam sputtering deposition method on epitaxially mismatched substrates of ferroelectric ceramics based on lead zirconate titanate (PZT, PbZr0.

In-medium broadening of nucleon resonances [PDF]

open access: yesPhysical Review C, 2001
We analyze the effects of an in-medium broadening of nucleon resonances on the exclusive photoproduction of mesons on nuclei as well as on the total photoabsorption cross sections in a transport calculation. We show that the resonance widths observed in semi-inclusive photoproduction on nuclei are insensitive to an in-medium broadening of nucleon ...

Broadening sound absorption coefficient with hybrid resonances [PDF]

open access: yesApplied Acoustics, 2020
Abstract In the last years, a great research effort has been focused on the noise mitigation at low frequencies. Membrane-type acoustic metamaterials (AMM) are one of the most promising solutions to meet the growing demand for low frequency sound absorbers.

Brillouin resonance broadening due to structural variations in nanoscale waveguides

open access: yesNew Journal of Physics, 2016
We study the impact of structural variations (that is slowly varying geometry aberrations and internal strain fields) on the width and shape of the stimulated Brillouin scattering (SBS) resonance in nanoscale waveguides.

Broadening of resonance lines by charged dislocations [PDF]

open access: yesJournal of Physics C: Solid State Physics, 1974
It is shown that the random electric fields of charge dislocations in insulators should cause appreciable broadening of sharp resonance lines such as spin-resonance signals. The degree of broadening is very sensitive to the screening of the dislocations by charged point defects.

Resonance Elastic Scattering and Interference Effects Treatments in Subgroup Method

open access: yesNuclear Engineering and Technology, 2016
Based on the resonance integral (RI) tables produced by the NJOY program, the conventional subgroup method usually ignores both the resonance elastic scattering and the resonance interference effects.

Exploring Experimental Isotope Scaling and Density Limit in Tokamak Transport

open access: yesPlasma
As it turns out, both isotope scaling and density limits are phenomena closely linked to fluid closure. The necessity to include ion viscosity arises for both phenomena. Thus, we have added ion viscosity to our model. The experimental isotope scaling has

Direct observation of narrow mid-infrared plasmon linewidths of single metal oxide nanocrystals

open access: yesNature Communications, 2016
Establishing the cause of inhomogeneous broadening would help to produce narrow ensemble localized surface plasmon resonance peaks, favourable for sensing applications. Here, Johns et al.
