Collinear Laser Spectroscopy of the Transitions in Helium-like B
Axel Buß, Konstantin Mohr, Volker Hannen +9
We report on hyperfine structure measurements of the fine-structure transitions in the spectrum of B ions. The h…
Rate coefficients for dielectronic recombination of N-like Ne
E. -O. Hanu, M. Lestinsky, E. B. Menz +16
Dielectronic recombination (DR) for the process Ne + e Ne was investigated in a merged-beams arrangement at the heavy-ion storage ring CRYRING@ESR…
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…
A Setup to Study Atomic State Population Dynamics and Optical Polarization at CRYRING@ESR
K. Mohr, R. Sánchez, W. Nörtershäuser +26
We present a recently established setup for laser spectroscopy at CRYRING@ESR at the GSI Helmholtz Centre for Heavy Ion Research. Here, laser spectroscopy can be performed on store…
X-ray emission associated with radiative recombination for Pb ions at threshold energies
B. Zhu, A. Gumberidze, T. Over +28
For bare lead ions, decelerated to the low beam energy of 10 MeV/u, the x-ray emission associated with radiative recombination (RR) at "cold collision" conditions has been studied…
Lifetimes and g-factors of the HFS states in H-like and Li-like bismuth
Volker Hannen, Jonas Vollbrecht, Zoran Andelkovic +23
The LIBELLE experiment performed at the experimental storage ring (ESR) at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany, has successfully determined the gr…
Observation of the hyperfine transition in lithium-like Bismuth : Towards a test of QED in strong magnetic fields
Matthias Lochmann, Raphael Jöhren, Christopher Geppert +21
We performed a laser spectroscopic determination of the hyperfine splitting (HFS) of Li-like and repeated the measurement of the HFS of H-like $^{…
Laser cooling of externally produced Mg ions in a Penning trap for sympathetic cooling of highly charged ions
Z. Andelkovic, R. Cazan, W. Nörtershäuser +7
We have performed laser cooling of Mg ions confined in a Penning trap. The externally produced ions were captured in flight, stored and laser cooled. Laser-induced fluorescence was…
