X-ray Absorption and Resonant X-ray Emission at the Carbon Edge of LiCO
John Vinson, Terrence Jach, Rainer Unterumsberger +2
While highly successful, density functional theory is known to have limitations owing to its neglect of many-body electron-electron interactions. This neglect leads to errors in th…
Titanium and titanium oxides at the K- and L-edges: validating theoretical calculations of X-ray absorption and X-ray emission spectra with measurements
Karina Bzheumikhova, John Vinson, Rainer Unterumsberger +5
Using well-calibrated experimental data we validate theoretical X-ray absorption spectroscopy (XAS) as well as X-ray emission spectroscopy (XES) calculations for titanium (Ti), tit…
Interaction of nanoparticle properties and X-ray analytical techniques
Rainer Unterumsberger, Philipp Hönicke, Yves Kayse +5
In this work, Pt-Ti core-shell nanoparticles (NP) of 2 nm to 3 nm in size and 30000 u \pm 1500 u as specified single particle mass, deposited on flat silicon substrates by means of…
Resonant X-ray Emission and Valence-band Lifetime Broadening in LiNO
John Vinson, Terrence Jach, Matthias Müller +2
X-ray absorption and resonant inelastic x-ray scattering measurements are carried out on lithium nitrate LiNO. The orbitals around the nitrogen atoms exhibit a large lifeti…
Experimental determination of line energies, line widths and relative transition probabilities of the Gadolinium L X-ray emission spectrum
Malte Wansleben, Yves Kayser, Philipp Hönicke +4
In this work the complete L-emission spectrum of gadolinium with respect to line energies, natural line widths, and relative transition probabilities was investigated using monochr…
Accurate experimental determination of Gallium K- and L3-shell XRF fundamental parameters
Rainer Unterumsberger, Philipp Hönicke, Julien L. Colaux +4
The fluorescence yield of the K- and L3-shell of gallium was determined using the radiometrically calibrated (reference-free) X-ray fluorescence instrumentation at the BESSY II syn…
