The Heidelberg compact electron beam ion traps
P. Micke, S. Kühn, L. Buchauer +16
Electron beam ion traps (EBIT) are ideal tools for both production and study of highly charged ions (HCI). In order to reduce their construction, maintenance, and operation costs w…
Coherent laser spectroscopy of highly charged ions using quantum logic
P. Micke, T. Leopold, S. A. King +6
Precision spectroscopy of atomic systems is an invaluable tool for the advancement of our understanding of fundamental interactions and symmetries. Recently, highly charged ions (H…
X-ray spectra of the Fe-L complex II: atomic data constraints from EBIT experiment and X-ray grating observations of Capella
Liyi Gu, Chintan Shah, Junjie Mao +14
The Hitomi results for the Perseus cluster have shown that accurate atomic models are essential to the success of X-ray spectroscopic missions, and just as important as knowledge o…
Detection of metastable electronic states by Penning trap mass spectrometry
Rima Xenia Schüssler, Hendrik Bekker, Martin Braß +19
State-of-the-art optical clocks achieve fractional precisions of and below using ensembles of atoms in optical lattices or individual ions in radio-frequency traps. Prom…
Atomic physics studies at the Gamma Factory at CERN
Dmitry Budker, José R. Crespo López-Urrutia, Andrei Derevianko +7
The Gamma Factory initiative proposes to develop novel research tools at CERN by producing, accelerating and storing highly relativistic, partially stripped ion beams in the SPS an…
High-Precision Determination of Oxygen-K Transition Energy Excludes Incongruent Motion of Interstellar Oxygen
M. A. Leutenegger, S. Kühn, P. Micke +25
We demonstrate a widely applicable technique to absolutely calibrate the energy scale of x-ray spectra with experimentally well-known and accurately calculable transitions of highl…
Observation of strong two-electron--one-photon transitions in few-electron ion
Moto Togawa, Steffen Kühn, Chintan Shah +22
We resonantly excite the series of O and O up to principal quantum number with monochromatic x rays, producing -shell holes, and observe their relaxatio…
Electronic bridge excitation in highly charged Th-229 ions
Pavlo V. Bilous, Hendrik Bekker, Julian Berengut +6
The excitation of the 8 eV Th isomer through the electronic bridge mechanism in highly charged ions is investigated theoretically. By exploiting the rich level scheme of o…
