A new apparatus for investigating collisions and chemical processes with ultracold NaK molecules — •Jakob Stalmann, Sebastian Anskeit, Fritz von Gierke, Kai K. Voges, and Silke Ospelkaus — Institute of Quantum Optics, Leibniz University Hannover

Ultracold molecular collisions feature many highly complex and still not understood phenomena, such as formation and loss of long-lived collisional complexes, molecular Feshbach resonances and chemical reactions.

Here, we present our efforts for the construction of a new experimental setup for the investigation of such collisional phenomena with ultracold 23Na39K ground-state molecules.

For ground-state molecule creation, we first produce optically trapped ultracold atomic ensembles from a dual-species Zeeman slower and MOT setup. The atoms are optically transported to a science chamber, where molecule preparation takes place by first creating weakly bound Feshbach molecules and subsequently transfering them into their ground state by a coherent Raman process. For detection of all educt and product particles of molecular collisions, our setup comprises a time of flight-velocity map imaging mass spectrometer in the science chamber. In combination with a state-selective pulsed laser ionization and fragmentation scheme this will allow us to resolve chemical reaction pathways, explore ultracold reaction dynamics and develop new quantum control techniques for chemical reaction steering.
