    "abstract": "Ultracold collisions between Cs atoms and Cs2 dimers in the electronic ground\nstate are observed in an optically trapped gas of atoms and molecules. The Cs2\nmolecules are formed in the triplet ground state by cw-photoassociation through\nthe outer well of the 0g-(P3/2) excited electronic state. Inelastic\natom-molecule collisions converting internal excitation into kinetic energy\nlead to a loss of Cs2 molecules from the dipole trap. Rate coefficients are\ndetermined for collisions involving Cs atoms in either the F=3 or F=4 hyperfine\nground state and Cs2 molecules in either highly vibrationally excited states\n(v\u0027=32-47) or in low vibrational states (v\u0027=4-6) of the a ^3 Sigma_u^+ triplet\nground state. The rate coefficients beta ~10^{-10} cm^3/s are found to be\nlargely independent of the vibrational and rotational excitation indicating\nunitary limited cross sections.",
