    "abstract": "We investigate collisional properties of lithium and cesium which are\nsimultaneously confined in a combined magneto-optical trap. Trap-loss\ncollisions between the two species are comprehensively studied. Different\ninelastic collision channels are identified, and inter-species rate\ncoefficients as well as cross sections are determined. It is found that loss\nrates are independent of the optical excitation of Li, as a consequence of the\nrepulsive Li$^*$-Cs interaction. Li and Cs loss by inelastic inter-species\ncollisions can completely be attributed to processes involving optically\nexcited cesium (fine-structure changing collisions and radiative escape). By\nlowering the trap depth for Li, an additional loss channel of Li is observed\nwhich results from ground-state Li-Cs collisions changing the hyperfine state\nof cesium.",
