Indeed, as for X-ray absorption and non-resonant X-ray emission spectroscopy the energy resolution is often limited by the relatively short life-time of the final state core-hole. As in RIXS a high energy core-hole is absent in the final state, this leads to intrinsically sharp spectra with energy and momentum resolution determined by the ...
Small-angle X-ray scattering (SAXS) probes structure in the nanometer to micrometer range by measuring scattering intensity at scattering angles 2θ close to 0°. X-ray reflectivity is an analytical technique for determining thickness, roughness, and density of single layer and multilayer thin films. Wide-angle X-ray scattering (WAXS), a ...
XAES – X-ray induced Auger electron spectroscopy; XANES – XANES, synonymous with NEXAFS (near edge X-ray absorption fine structure) XAS – X-ray absorption spectroscopy; X-CTR – X-ray crystal truncation rod scattering; X-ray crystallography; XDS – X-ray diffuse scattering; XES – X-ray emission spectroscopy
The photon-in-photon-out process may be thought of as a scattering event. When the x-ray energy corresponds to the binding energy of a core-level electron, this scattering process is resonantly enhanced by many orders of magnitude. This type of X-ray emission spectroscopy is often referred to as resonant inelastic X-ray scattering (RIXS).
X-ray emission spectroscopy (XES) is a form of X-ray spectroscopy in which a core electron is excited by an incident x-ray photon and then this excited state decays by emitting an x-ray photon to fill the core hole. The energy of the emitted photon is the energy difference between the involved electronic levels.
The X-ray absorption near-edge structure , introduced in 1980 and later in 1983 and also called NEXAFS (near-edge X-ray absorption fine structure), which are dominated by core transitions to quasi bound states (multiple scattering resonances) for photoelectrons with kinetic energy in the range from 10 to 150 eV above the chemical potential ...
Elastic scattering is a form of particle scattering in scattering theory, nuclear physics and particle physics. In this process, the internal states of the particles involved stay the same. In the non-relativistic case, where the relative velocities of the particles are much less than the speed of light , elastic scattering simply means that ...
Small-angle X-ray scattering (SAXS) is a small-angle scattering technique by which nanoscale density differences in a sample can be quantified. This means that it can determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes and characteristic distances of partially ordered materials.
