Spectroscopy of Rydberg states in ultra cold ytterbium — •Christian Halter, Mustafa Jumaah, Laura Sucke, Tobias Franzen, Bastian Pollklesener, Cristian Bruni, and Axel Görlitz — Heinrich-Heine-Universität Düsseldorf, Düsseldorf, Deutschland

In recent years Rydberg atoms with their special features, like dipole-dipole interaction or van-der-Waals blockade, have become more and more important for quantum optics. Particularly ultra cold Rydberg atoms are of great interest for the investigation of long range interaction. A special feature of ytterbium is that due to its two valance electrons atoms in Rydberg state can be easily manipulated and imaged using optical fields. A first step towards studies of ultra cold ytterbium is to gain precise knowledge on the Rydberg states. Here we present a spectroscopy study of the Rydberg states of ultra cold ytterbium. For the detection of the Rydberg states we are using the induced loss of atoms in a MOT when atoms are excited to a Rydberg state. Using this method we could measure several energy levels of Rydberg states.
