On the Stark effect of NaK — •Andreas Gerdes, Horst Knöckel, and Eberhard Tiemann — Institut für Quantenoptik, Gottfried Wilhelm Leibniz Universität Hannover, Welfengarten 1, 30167 Hannover
After preliminary measurements in a heatpipe setup [1] and characterization of our new molecular beam aparatus we show the next step of investigation concerning the heteronuclear molecule NaK. A homogeneous electric field in the detection zone will modify the rotational structure of the spectral lines under consideration. For a model description of the line shapes, not only the molecular Stark effect of the absolute ground state X 1Σ+ of the molecule, but also the splitting of the excited state B 1Π has to be taken into account. Results of our investigation into this direction will be shown. A comparison with theoretical predictions is possible [2]. Prospects heading to the target molecule KRb will be discussed.
