Wereport on the creation of ultracold heteronuclear molecules assembled fromfermionic ⁴⁰K and bosonic ⁸⁷Rb atoms in a 3D opticallattice. Molecules are produced at a heteronuclear Feshbach resonance onboth the attractive and the repulsive sides of the resonance.We precisely determine the binding energy of the heteronuclear moleculesfrom rf spectroscopy across the Feshbach resonance. We characterize thelifetime of the molecular sample as a function of magneticfield and measure lifetimes between 20 and 120 ms. The efficiencyof molecule creation via rf association is measured and isfound to decrease as expected for more deeply bound molecules.
