Pair creation in heavy ion channeling
Nikolay A. Belov, Zoltán Harman
Heavy ions channeling through crystals with multi-GeV kinetic energies can create electron-positron pairs. In the framework of the ion, the energy of virtual photons arising from t…
Astrophysical line diagnosis requires non-linear dynamical atomic modeling
Natalia S. Oreshkina, Stefano M. Cavaletto, Christoph H. Keitel +1
Line intensities and oscillator strengths for the controversial 3C and 3D astrophysically relevant lines in neonlike Fe ions are calculated. We show that, for strong x-ra…
High-precision measurement of the atomic mass of the electron
Sven Sturm, Florian Köhler, Jacek Zatorski +6
The quest for the value of the electron's atomic mass has been subject of continuing efforts over the last decades. Among the seemingly fundamental constants which parameterize the…
Broadband high-resolution x-ray frequency combs
Stefano M. Cavaletto, Zoltan Harman, Christian Ott +3
Optical frequency combs have had a remarkable impact on precision spectroscopy. Enabling this technology in the x-ray domain is expected to result in wide-ranging applications, suc…
