Frequency-comb based collinear laser spectroscopy of Be for nuclear structure investigations and many-body QED tests
A. Krieger, W. Nörtershäuser, Ch. Geppert +13
Absolute transition frequencies of the transitions in Be were measured with a frequency comb in stable and short…
Precision Test of Many-Body QED in the Be Fine Structure Doublet Using Short-Lived Isotopes
Wilfried Nörtershäuser, Christopher Geppert, Andreas Krieger +13
Absolute transition frequencies of the transitions in Be were measured for the isotopes Be. The fine st…
Isotope shift of Ca in the transition
C. Gorges, K. Blaum, N. Frömmgen +8
We report on improved isotope shift measurements of the isotopes Ca in the (D2) transition usin…
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…
Nuclear Charge Radius of Be
Andreas Krieger, Klaus Blaum, Mark L. Bissell +13
The nuclear charge radius of Be was precisely determined using the technique of collinear laser spectroscopy on the transition in the Be$…
