Autor: Krieger, A., Nörtershäuser, W., Geppert, Ch., Blaum, K., Bissell, M. L., Frömmgen, N., Hammen, M., Kreim, K., Kowalska, M., Krämer, J., Neugart, R., Neyens, G., Sánchez, R., Tiedemann, D., Yordanov, D. T., Zakova, M.

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. Q
