Frequency-comb based collinear laser spectroscopy of Be for nuclear structure investigations and many-body QED tests
/ Krieger, A ; Nörtershäuser, W ; Geppert, Ch ; Blaum, K ; Bissell, M L ; Frömmgen, N ; Hammen, M ; Kreim, K ; Kowalska, M (CERN) ; Krämer, J et al.
Absolute transition frequencies of the $2s\,^2{\rm{S}}_{1/2}$ $\rightarrow$ $2p\,^2{\rm{P}}_{1/2,3/2}$ transitions in Be$^+$ were measured with a frequency comb in stable and short-lived isotopes at ISOLDE (CERN) using collinear laser spectroscopy. Quasi-simultaneous measurements in copropagating and counterpropagating geometry were performed to become independent from acceleration voltage determinations for Doppler-shift corrections of the fast ion beam.

Isotope shift measurements in the 2s(1/2) -> 2p(3/2) transition of Be+ and extraction of the nuclear charge radii for Be-7,Be-10,Be-11

We have performed isotope shift measurements in the 2s(1/2) -> 2p(3/2) transition of Be+ ions using advanced collinear laser spectroscopy with two counter-propagating laser beams. Measurements involving a frequency comb for laser stabilization and absolute frequency determination allowed us to determine the isotope shifts with an accuracy of 2 MHz. [...]
