We investigate the formation of weakly bound, electronically excited, heteronuclear 6 Li 40 K * molecules by single-photon photoassociation in a magneto-optical trap. We performed trap loss spectroscopy within a range of 325 GHz below the Li(2 S 1/2 )+K(4 P 3/2 ) and Li(2 S 1/2 )+K(4 P 1/2 ) asymptotic states and observed more than 60 resonances, which we identify as rovibrational levels of 7 of 8 attractive long-range molecular potentials. The long-range dispersion coefficients and rotational constants are derived. We find large molecule formation rates of up to ∼3.5 × 10 7 s − 1 , which are shown to be comparable to those for homonuclear 40 K 2 * . Using a theoretical model we infer decay rates to the deeply bound electronic ground-state vibrational level X 1 Σ + ( v '=3) of ∼5 × 10 4 s −1 . Our results pave the way for the production of ultracold bosonic ground-state 6 Li 40 K molecules which exhibit a large intrinsic permanent electric dipole moment.We investigate the formation of weakly bound, electronically excited, heteronuclear 6 Li 40 K * molecules by single-photon photoassociation in a magneto-optical trap.
