Abstract
We have converted an ultracold Fermi gas of atoms into an ultracold gas of molecules by adiabatic passage through a Feshbach resonance. Approximately molecules in the least-bound, , vibrational level of the 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.
