Abstract: We have converted an ultracold Fermi gas of $^{6}\mathrm{L}\mathrm{i}$ atoms into an ultracold gas of $^{6}\mathrm{L}\mathrm{i}_{2}$ molecules by adiabatic passage through a Feshbach resonance. Approximately $1.5\ifmmode\times\else\texttimes\fi{}{10}^{5}$ molecules in the least-bound, $v=38$, vibrational level of the ${X}^{1}{\ensuremath{\Sigma}}_{g}^{+}$ singlet state are produced with an efficiency of 50%. The molecules remain confined in an optical trap for times of up to 1 s before we dissociate them by a reverse adiabatic sweep.
