Cold quantum gases, when acted upon by electromagnetic fields, can give riseto samples where isolated atoms coexist with dimers or trimers, which raisesthe question of the interactions between these various constituents. Here weperform microwave photoassociation in a degenerate gas of $^{87}$Rb atoms tocreate weakly-bound dimers in their electronic ground state. From thedensity-induced shift of the photoassociation line, we measure the atom-dimerscattering length for the two least-bound states of the molecular potential. Wealso determine the complete energy diagram of one hyperfine manifold of theleast-bound state, which we accurately reproduce with a simple model.
