dc.description.abstract The spectra of the high-lying vibrational levels of the $A\sp1\Sigma\sbsp{u}{+}$ and $1\sp3\Sigma\sbsp{g}{+}$ singly excited states of both $\sp6\rm Li\sb2$ and $\sp7\rm Li\sb2$ are obtained via photoassociation of colliding ultracold atoms confined in a magneto-optical trap. The least bound state of the $a\sp3\Sigma\sbsp{u}{+}$ ground state potential, obtained by two-photon photoassociative spectroscopy, is also presented for both $\sp7\rm Li\sb2$ and $\sp6\rm Li\sb2$. The vibrational levels have resolved hyperfine structure, whose relative energy splittings and transition strengths are accurately modeled. The photoassociative spectra are used to precisely determine both the singlet and triplet s-wave scattering lengths for both isotopes, which are important parameters in systems designed to observe quantum degenerate effects and Bose-Einstein condensation.
