In our previous work we investigated electronically non-adiabatic effects in $\rm Cl~(^{2}P_{3/2,1/2})+D_{2}$ using crossed molecular beam scattering coupled with velocity mapped ion imaging. The prior experiments placed limits on the cross-section f

We have created bright matter wave solitons by using a Feshbach resonance to tune the interactions in a Bose–Einstein condensate of 7 Li. The solitons are made to propagate in a one-dimensional potential formed by a focused laser beam. We observed

Attraction between atoms in a Bose-Einstein-Condensate renders the condensate unstable to collapse. Confinement in an atom trap, however, can stabilize the condensate for a limited number of atoms, as was observed with 7Li, but beyond this number, th

A slow atom source, which does not rely on lasers, has been developed and characterized. The device, acting as an atomic low-pass velocity filter, utilizes permanent magnets to passively select the slow atoms present in a thermal atomic beam. Slow at

We have produced a molecular Bose-Einstein condensate from fermionic /sup 6/Li atoms. Optical molecular spectroscopy is used to probe the many-body state in the BCS/BEC crossover region. Preliminary results indicate that the molecular contribution is

We have used optical molecular spectroscopy to probe the many-body state of paired $^6$Li atoms near a broad Feshbach resonance. The optical probe projects pairs of atoms onto a vibrational level of an excited molecule. The rate of excitation enables

Atomic Feshbach resonances have recently been used to produce a strongly interacting Fermi gas, where the BCS/BEC crossover can be explored. We have used both narrow and broad Feshbach resonances to convert a quantum degenerate Fermi gas of 6Li atoms

We have converted a quantum degenerate Fermi gas of 6Li atoms into an ultracold gas of 6Li2 molecules using a Feshbach resonance. Up to 1.5 times 105 molecules are produced with 50% efficiency, and optically confined for up to 1 s

We have converted an ultracold Fermi gas of $^6$Li atoms into an ultracold gas of $^6$Li$_2$ molecules by adiabatic passage through a Feshbach resonance. Approximately $1.5 \times 10^5$ molecules in the least-bound, $v = 38$, vibrational level of the
