We report an upper bound to the ionization energy of Rb-85(2) of 31 348.0(6) cm(-1), which also provides a lower bound to the dissociation energy D-0 of Rb-85(2)+ of 6 307.5(6) cm(-1). These bounds were measured by the onset of autoionization of the excited states of Rb-85(2) below the 5s + 7p atomic limit. We form Rb-85(2) molecules via photoassociation of ultracold Rb-85 atoms and subsequently excite the molecules by single-photon uv transitions to states above the ionization threshold.
