摘要：

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