Abstract
We have improved the theoretical triplet ground-state potential of Li- 7(2) by means of an inverse perturbation analysis, and find that the d iatomic scattering length for Li-7 atoms in the F = 2, m(F) = 2 ground -state hyperfine level is negative. The consequences of this result fo r achieving Bose-Einstein condensation in a trapped ultracold Li-7 gas sample are addressed.
