Abstract
We report the production of ultracold heteronuclear Cs∗ Yb molecules through one-photon photoassociation applied to an ultracold atomic mixture of Cs and Yb confined in an optical dipole trap. We use trap-loss spectroscopy to detect molecular states below the Cs (2 P1/2) + Yb(1 S0) asymptote. For 133Cs 174Yb, we observe 13 rovibrational states with binding energies up to ∼500 GHz. For each rovibrational state we observe two resonances associated with the Cs hyperfine structure and show that the hyperfine splitting in the diatomic molecule decreases for more deeply bound states. In addition, we produce ultracold fermionic 133Cs 173Yb and bosonic 133Cs 172Yb and 133Cs 170Yb molecules. From mass scaling, we determine the number of vibrational levels supported by the 2(1/2) excited-state potential to be 154 or 155.
