An ultracold Bose-Fermi mixture of 133Cs and 6Li is well suited for the study of a dipolar gas of ultracold ground state molecules with large dipole moments. The formation of Feshbach molecules is a prerequisite for the creation of ground state molecules by coherent transfer through a stimulated Raman adiabatic passage (STIRAP). We report on the formation of 6Li133Cs Feshbach molecules via the magneto-association technique. The Feshbach molecules are investigated at three s-wave resonances with widths of 0.37G, 4.22G and 57.45G. We compare the formation efficiency and lifetime of the molecules for the three different resonances and identify the best conditions for STIRAP transfer.
