Abstract

We determine the energies of twelve vibrational levels lying within 20 GHz of the lowest dissociation limit of 85Rb2with two-color photoassociation spectroscopy of ultracold 85Rb atoms. The levels lie in an energy range for which singlet and triplet states are mixed by the hyperfine interaction. We carry out a coupled channels bound state analysis of the level energies, and derive accurate values for 85Rb2interaction parameters. The information obtained is sufficient to allow for quantitative calculations of arbitrary Rb ultracold collision properties.
