Polarization-Dependent Disappearance of a Resonance Signal -- Indication for Optical Pumping in a Storage Ring?
W. Nörtershäuser, A. Surzhykov, R. Sánchez +10
We report on laser spectroscopic measurements on Li ions in the experimental storage ring ESR at the GSI Helmholtz Centre for Heavy Ion Research. Driving the $2s\,^3\!{S}_1\;(F…
Test of Time Dilation Using Stored Li+ Ions as Clocks at Relativistic Speed
Benjamin Botermann, Dennis Bing, Christopher Geppert +14
We present the concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of beta = v/c = 0.338 in the storage ring ESR at Darmsta…
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 $^{…
Modern Ives-Stilwell Experiments At Storage Rings: Large Boosts Meet High Precision
G. Gwinner, B. Botermann, C. Geppert +14
We give a brief overview of time dilation tests using high-resolution laser spectroscopy at heavy-ion storage rings. We reflect on the various methods used to eliminate the first-o…
Comment on "Missing Transverse-Doppler Effect in Time-Dilation Experiments with High-Speed Ions"
G. Saathoff, S. Reinhardt, R. Holzwarth +14
In an article "Missing Transverse-Doppler Effect in Time-Dilation Experiments with High-Speed Ions" by S. Devasia [arXiv:1003.2970v1], our recent Doppler shift experiments on fast…
