Abstract
The triplet s-wave scattering length of [Formula Presented] is determined using two-photon photoassociative spectroscopy of the diatomic a[Formula Presented] state of [Formula Presented]. The measured binding energy of the highest-lying bound state, combined with knowledge of the potential, determines the s-wave scattering length to be (-2160±250)[Formula Presented], where [Formula Presented] is the Bohr radius. This extraordinarily large scattering length signifies a near-threshold resonance. A complete table of singlet and triplet scattering lengths for collisions involving [Formula Presented] and [Formula Presented] determined from this and our previous spectroscopic investigations is given.
