Our paper „Application of the Continuous Stern-Gerlach Effect for Laser Spectroscopy of the 40Ar13+ Fine Structure in a Penning Trap“ by A. Egl et al. has been published in Physical Review Letters. This work has been carried out in collaboration with the group of Sven Sturm from the Max-Planck-Institute for Nuclear Physics in Heidelberg and reports on a new laser spectroscopy technique to measure M1 transitions on single highly charged ion in a Penning trap by detecting the laser-induced spin flip using the continuous Stern-Gerlach effect. The figure shows the schematic setup of the experiment at the MPIK in Heidelberg.
