Implementation of a pulsed nozzle in a cold reactive scattering setup — •Hanna-Sophie Maier, Jonas Grzesiak, Frank Stienkemeier, and Marcel Mudrich — Physikalisches Institut, Universität Freiburg, Hermann-Herder-Str.3, 79104 Freiburg

The investigation of cold reactive scattering processes requires a dense and cold beam of metastable atoms and molecules. To this end a pulsed, supersonic and cryogenic nozzle including a home built dielectric barrier discharge (DBD) is used. We combine the beam of metastables with a second velocity-tunable molecular beam generated by a rapidly rotating nozzle. We present the characterization of the cold and dense beam of metastable atoms from the optimized pulsed nozzle setup. Moreover first results on reactive scattering of the metastables in the merged beam geometry are shown.
