Photoassociation is the process in which two colliding atoms absorb a photon to form an
excited molecule. The development of laser-cooling techniques for producing gases at …

The authors review progress in understanding the nature of atomic collisions occurring at
temperatures ranging from the millidegrees Kelvin to the nanodegrees Kelvin regime. The …

We have measured ap-wave Feshbach resonance in a single-component, ultracold Fermi
gas of K 40 atoms. We have used this resonance to enhance the normally suppressed p …

By performing high-resolution two-color photoassociation spectroscopy, we have
successfully determined the binding energies of several of the last bound states of the …

We review topics of current interest in the physics of electronic, atomic and molecular
scattering in the vicinity of thresholds. Starting from phase space arguments, we discuss the …

The new spectroscopic technique of photoassociation of ultracold atoms is reviewed, with an
emphasis on connecting this area to traditional bound-state molecular spectroscopy. In …

We report the observation of three p-wave Feshbach resonances of Li 6 atoms in the lowest
hyperfine state f= 1∕ 2. The positions of the resonances are in good agreement with theory …

A general formalism is derived for analytically representing the scattering properties of
ultracold atoms subject to one or more resonant photoassociation lasers. The resulting …

We report Bose-Einstein condensation of Sr 84 in an optical dipole trap. Efficient laser
cooling on the narrow intercombination line and an ideal s-wave scattering length allow the …

We have calculated the time-dependent dynamics of two ultracold Na atoms in an atom trap
where a time-dependent magnetic field B (t) moves a Feshbach resonance state across the …
