Trap loss in a double species MOT of Yb and Rb — •Maximilian Madalinski, Cristian Bruni, Frank Münchow, and Axel Görlitz — Institut für Experimentalphysik, HHU Düsseldorf, 40225 Düsseldorf
Ultracold mixtures of two atomic species are an excellent environment to study their interspecies collisions, to produce exotic heteronuclear molecules or to study double species quantum gases. In our experiment we are able to trap seperately 109 Rb and 107 Yb atoms but we observe a strong loss of Yb in the combined MOT. The Yb MOT uses the 1S0 to 3P1 intercombination transition at 555.8 nm. The production of excited molecules was already achieved in this configuration. Here we present a method of determining the trap loss coefficients of Yb through Rb in our combined trap. Since Yb has trapable bosonic and fermionic isotopes collisions in every combination can be explored.
