"Triplet s-wave resonance in Li6 collisions and scattering lengths of Li6 and Li7." <i>Physical Review A,</i> 55, no. 5 (1997) American Physical Society: 3797-3801. http://dx.doi.org/10.1103/PhysRevA.55.R3299.https://hdl.handle.net/1911/79415The triplet s-wave scattering length of Li6 is determined using two-photon photoassociative spectroscopy of the diatomic a3Σ+u state of Li26. 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)a0, where a0 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 Li6 and Li7 determined from this and our previous spectroscopic investigations is given.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
