Scattering by Interstellar Dust Grains. II. X-Rays

open access: yes, 2003
Scattering and absorption of X-rays by interstellar dust is calculated for a model consisting of carbonaceous grains and amorphous silicate grains. The calculations employ realistic dielectric functions with structure near X-ray absorption edges, with ...

Development of powder diffraction apparatus for small-angle X-ray scattering measurements [PDF]

open access: yes, 2013
A novel type of X-ray collimation system attached to commercial powder diffractometers makes the structural characterization of nanomaterials possible in a wide size range from

Heterodyne x-ray diffuse scattering from coherent phonons

open access: yesStructural Dynamics, 2017
Here, we report Fourier-transform inelastic x-ray scattering measurements of photoexcited GaAs with embedded ErAs nanoparticles. We observe temporal oscillations in the x-ray scattering intensity, which we attribute to inelastic ...

Characterizing the ionization potential depression in dense carbon plasmas with high-precision spectrally resolved x-ray scattering

open access: yesPlasma Physics and Controlled Fusion, 2018
We discuss the possibility of obtaining highly precise measurements of the ionization potential depression in dense plasmas with spectrally resolved x-ray scattering, while simultaneously determining the electron temperature and the free electron density.

Resonant X-Ray Scattering Studies of Charge Order in Cuprates [PDF]

open access: yes, 2015
X-ray techniques have been used for more than a century to study the atomic and electronic structure in practically any type of material. The advent of correlated electron systems, in particular complex oxides, brought about new scientific challenges and

Parameter estimation for X-ray scattering analysis with Hamiltonian Markov Chain Monte Carlo

open access: yesJournal of Synchrotron Radiation, 2022
Bayesian-inference-based approaches, in particular the random-walk Markov Chain Monte Carlo (MCMC) method, have received much attention recently for X-ray scattering analysis.

Comparative study of different scattering geometries for the proposed Indian X-ray polarization measurement experiment using Geant4

open access: yes, 2010
Polarization measurements in X-rays can provide unique opportunity to study the behavior of matter and radiation under extreme magnetic fields and extreme gravitational fields. Unfortunately, over past two decades, when X-ray astronomy witnessed multiple

Small-Angle Scattering of X-Rays from Extragalactic Sources by Dust in Intervening Galaxies [PDF]

open access: yes, 1998
Gamma-ray bursts are now known to be a cosmological population of objects, which are often accompanied by X-ray and optical afterglows. The total energy emitted in the afterglow can be similar to the energy radiated in the gamma-ray burst itself.

Magnetic X-Ray Scattering

open access: yesActa Physica Polonica A, 1994
It was proposed in the 1950's that X-rays could be used to probe magnetization densities. After some experimental demonstrations of the technique, applications have shown that tle use of magnetic X-ray scattering com-bined with synchrotron radiation can lead to important new discoveries in the magnetism of solid materials.
