Stringent Constraints on New Pseudoscalar & Vector Bosons from Precision Hyperfine Splitting Measurements
Cedric Quint, Fabian HeiÃe, Joerg Jaeckel +3
Axion-like particles and similar new pseudoscalar as well as vector bosons coupled to nucleons and electrons are predicted to lead to spin-dependent forces in atoms and ions. We ar…
Enhanced One-Color-Two-Photon Resonant Ionization in Highly Charged Ions by Fine-Structure Effects
Moto Togawa, Chunhai Lyu, Chintan Shah +25
Ultraintense pulses from X-ray free-electron lasers can drive, within femtoseconds, multiple processes in the inner shells of atoms and molecules in all phases of matter. The ensui…
Testing strong-field QED to second-order in the highly correlated atomic system berylliumlike Pb78+ by electron-ion recombination spectroscopy
S. Schippers, C. Brandau, S. Fuchs +33
A low-energy storage ring with an ultracold electron cooler has been coupled with a heavy-ion accelerator facilitating high-resolution electron-ion collision spectroscopy of the he…
Dielectronic recombination studies of ions relevant to kilonovae and non-LTE plasma
Suvam Singh, Zoltán Harman, Christoph H. Keitel
This study presents calculations of rate coefficients, resonance strengths, and cross sections for the dielectronic recombination (DR) of , , $\text{Te…
Testing inter-electronic interaction in lithium-like tin
Jonathan Morgner, Vladimir A. Yerokhin, Charlotte M. Konig +9
Magnetic moments of bound-electron systems are a sensitive tool for testing fundamental interactions. factors of lithium-like ions have been rigorously studied in recent years,…
Periodic table for highly charged ions
Chunhai Lyu, Christoph H. Keitel, Zoltán Harman
Mendeleev's periodic table successfully groups atomic elements according to their chemical and spectroscopic properties. However, it becomes less sufficient in describing the elect…
