photoionizationX-rayspectroscopyIn experiments at the high-power Z-facility at Sandia National Laboratory in Albuquerque, New Mexico, we have been able to produce a low density photoionized laboratory plasma of Fe mixed with NaF. The conditions in the experiment allow a meaningful comparison with X...

Binding energy (BE) referencing is critical to the reliability of chemical analysis performed by X-ray photoelectron spectroscopy. Although the procedure is straightforward for metallic samples, no universal solution is available for insulators, wherein a build-up of positive charge during photoemission ...
In an intense X-ray free-electron laser (XFEL) pulse, atoms are sequentially ionised by multiple X-ray photons. Photoionisation generally induces an alignment of the electron cloud of the produced atomic ion regarding its orbital-angular-momentum project

Inner-shell absorption of an X-ray photon can—depending on the photon energy and atomic species—also create multiple charges on a molecule due to Auger cascades. However, among the many studies on 3D momentum imaging using X-ray ionization, only a few of them have studied somewhat larger ...
(Fig.1). The S 2pphotoionization with a soft x-ray pulse, of photon energyhv, leads to a photoelectron with kinetic energyEkin = hv − Ebind. The molecular UV photoexcitation changes the local charge density at the probed atom (Fig.1bbottom), which leads to a specific ESCS....
Here, X-ray photon energy is insufficient for a direct K-shell photoionization and the initial absorption channel of the ground state (K2L8) is L-shell photoionization. Although the ionization rate is small, a significant portion of atoms are excited to the K2L7 state owing to the large ...
