Rate coefficients for dielectronic recombination of N-like Ne
E. -O. Hanu, M. Lestinsky, E. B. Menz +16
The paper reports measurements of dielectronic recombination rate coefficients for N‑like neon (Ne³⁺ + e⁻ → Ne²⁺) using a merged‑beams setup at the CRYRING@ESR storage ring, coveri…
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…
Quantum Electrodynamics in Strong Electromagnetic Fields: Substate Resolved K Transition Energies in Helium-like Uranium
Philip Pfäfflein, Günter Weber, Steffen Allgeier +34
Using novel metallic magnetic calorimeter detectors at the CRYRING@ESR, we recorded X-ray spectra of stored and electron cooled helium-like uranium (U) with an unmatched sp…
