Improved setup of a rotating nozzle for producing slow and cold molecules — •Matthias Strebel, Tim Eichhorn, Marcel Mudrich, and Frank Stienkemeier — Physikalisches Institut, Universität Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg, Germany

In order to study reactive and non reactive collisions between atoms and molecules at very low scattering energies we plan to combine a magneto-optical trap (MOT) for ultracold lithium atoms with a setup for producing beams of cold molecules at low velocities in the laboratory frame. A slow molecular beam is produced with an improved setup by means of a supersonic expansion from a rapidly rotating nozzle.

Technical details of the device as well as the results of first measurements will be presented. An electrostatic quadrupole guide is implemented in order to efficiently transfer the molecules via the Stark effect into the detection region.
