This thesis reports on the first investigation of inelastic collision processes between ultra-cold lithium and cesium atoms. For this purpose, a combined magneto-optical trap for both species is realized. Densities of n_L_i#approx#10"1"1 atoms/cm"3 and n_C_s#approx#10"1"0 atoms/cm"3 at temperatures of T_L_i#approx#1 mK and T_C_s#approx#100 #mu#K are attained. The losses occuring at simultaneous trapping allow one to investigate different inelastic collision processes. These processes are identified and quantified by studying the temporal evolution of the number of trapped atoms at different operation conditions of the traps. Collision processes involving cesium in the optically excited state are observed, the m...
