The photoionization of xenon atoms in the 70–100 eV range reveals several fascinating physical phenomena such as a giant resonance induced by the dynamic rearrangement of the electron cloud after photon absorption, an anomalous branching ratio between intermediate Xe+ states separated by the spin-orbit interaction and multiple Auger decay processes. These phenomena have been studied in the past, u
The use of protective barriers to isolate a metal surface from an aggressive environment is a common way to inhibit its degradation. We used ambient pressure x-ray photoelectron spectroscopy to assess in real time the evolution of the copper surface and the contextual protective action of 2D material coatings (graphene and hexagonal boron nitride) towards copper oxidation. In an isobaric experimen
Interest in the distinctive features of early Christian manuscripts (e.g. codex format, staurogram, nomina sacra, handwriting, and lectional signs) has increased significantly over the last decade. They are no longer merely identified and compared, but also put into a sociocultural context of early Christian scribal habits and reading culture. Similarly, more attention is constantly being directed
Nuclear Quadrupole Resonance (NQR) is a radio frequency (RF) technique that can be used to detect the presence of quadrupolar nuclei, such as the 14N nucleus prevalent in many explosives and narcotics. The technique has been hampered by low signal-to-noise ratios and is further aggravated by the presence of RF interference (RFI). To ensure accurate detection, proposed detectors should exploit the
Vilken roll spelar de arbetslösa sjukskrivna? Är de arbetslösa, arbetssökande eller sjuka? I uppsatsen diskuteras rollsociologi, arbetslöshet och sjukskrivning, samt vilken roll arbetslösa sjukskrivna identifierar sig med.
