We have determined the fine structure splitting of the 2p states in Be⁺ ions for stable and short-lived isotopes at COLLAPS. This leads to an improvement of the accuracy of the Be-9 fine structure splitting by two orders of magnitude go

Our new article about the extraction of magnetic dipole and electric quadrupole moments of odd cadmium isotopes with masses 107-123 amu appeared in the European Physical Journal D and was distinguished as an EPJD Highlight. go

Our new publication entitled “An improved value for the hyperfine splitting of hydrogen-like ²⁰⁹Bi⁸²⁺” appeared in J. Phys. B and presents the most accurate measurement of a hyperfine transition in a heavy hydrogen-like ion that has so far been accomplished. go

The establishment of our laboratory at the TU Darmstadt and the set-up of the experiment for accurate high-voltage measurements (ALIVE: Accurate Laser Involved Voltage Evaluation) are progressing. A Ca⁺ ion source and the first part of the required beam line have been installed go

The new issue of the Journal “International Innovation” has the title “Into the unknown and back again”. It contains a portrait of LaserSpHERe go
