Atomic scattering of metastable neon atoms — •Christian Cop and Reinhold Walser — Institute for Applied Physics, TU Darmstadt, Germany

Currently, many experiments are directed towards Bose-Einstein-Condensations of novel elements besides the alkalies: noble gases [1], rare-earth-gases and composite molecules. In the group of G. Birkl at the University of Darmstadt, the prospects for cooling metastable neon atoms (Ne*) to degeneracy are investigated experimentally [2]. Already the condensation of hydrogen (H) as well as metastable helium (He*) were affected by Penning ionization. Therefore it is also of crucial importance to investigate the collision properties of Ne*-atoms and asses the ratio of good to bad collisions. We have developed a numerical code for multichannel scattering and present recent results.
