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…
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…
Sub-milliKelvin spatial thermometry of a single Doppler cooled ion in a Paul trap
S. Knünz, M. Herrmann, V. Batteiger +3
We report on observations of thermal motion of a single, Doppler-cooled ion along the axis of a linear radio-frequency quadrupole trap. We show that for a harmonic potential the th…
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…
Precision spectroscopy of the 3s-3p fine structure doublet in Mg+
V. Batteiger, S. Knünz, M. Herrmann +7
We apply a recently demonstrated method for precision spectroscopy on strong transitions in trapped ions to measure both fine structure components of the 3s-3p transition in 24-Mg+…
Frequency Metrology on single trapped ions in the weak binding limit: The 3s1/2-3p3/2 transition in 24-Mg+
M. Herrmann, V. Batteiger, S. Knünz +3
We demonstrate a method for precision spectroscopy on trapped ions in the limit of unresolved motional sidebands. By sympathetic cooling of a chain of crystallized ions we suppress…
Enhanced dielectronic recombination of lithium-like Ti19+ ions in external ExB fields
Timo Bartsch, Stefan Schippers, Michael Beutelspacher +9
Dielectronic recombination(DR) of lithium-like Ti19+(1s2 2s) ions via 2s->2p core excitations has been measured at the Heidelberg heavy ion storage ring TSR. We find that not only…
