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…
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$…
Calibration of the ISOLDE acceleration voltage using a high-precision voltage divider and applying collinear fast beam laser spectroscopy
A. Krieger, Ch. Geppert, R. Catherall +9
A high-voltage divider with accuracy at the ppm level and collinear laser spectroscopy were used to calibrate the highvoltage installation at the radioactive ion beam facility ISOL…
