We present two-photon photoassociation to the least-bound vibrational level of the X1Σ+g electronic ground state of the 86Sr2 dimer and measure a binding energy of Eb = −83.00 (7)(20) kHz. Because of the very small binding energy, this is a halo state corresponding to the scattering resonance for tw...
