SYCM: Heteronuclear cold molecules

SYCM 2: Heteronuclear cold molecules

SYCM 2.4: Hauptvortrag

Samstag, 5. März 2005, 16:00–16:30, HU Audimax

Mixture of ultracold lithium and cesium and photoassociation of cold LiCs — •Matthias Weidemüller¹, Stephan Kraft¹, Jörg Lange¹, Peter Staanum^1,2, and Roland Wester¹ — ¹Physikalisches Institut der Universität Freiburg, 79104 Freiburg — ²Institut für Quantenoptik, Universität Hannover, 30167 Hannover

We trap a mixture of ultracold lithium and cesium atoms in a quasi-electrostatic trap formed by the focus of a CO₂ laser beam. Elastic and inelastic processes between the two different gases are studied in detail. Possible routes to the formation of cold heteronuclear molecules in low vibrational states will be discussed and the status of the experiment will be presented.
