Bosonic and fermionic metastable neon atoms in optical and magnetic traps — •Jan Schütz, Eva-Maria Kriener, Wouter van Drunen, Norbert Herschbach, and Gerhard Birkl — Institut für Angewandte Physik, Technische Universität Darmstadt, Schlossgartenstr. 7, 64289 Darmstadt
We experimentally investigate the interactions of laser cooled metastable neon atoms in a magneto-optical trap (MOT), in magnetic traps, and optical dipole traps. For the bosonic isotopes 20Ne and 22Ne we determined the rate coefficients for inelastic collisions and the scattering lengths for atoms in the metastable 3P2 state.
As the next step, we succeeded in optically trapping both bosonic isotopes in the metastable 3P0 state and are currently determining the two-body loss coefficients.
Recent extensions of our laser configuration allow us to trap the fermionic isotope 21Ne and mixtures of bosonic and fermionic isotopes. We report on the status of these experiments.
