New Technique for Laser Spectroscopy on Highly Charged Ions Demonstrated

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. go
