This review is concerned with the physics and chemistry associated with the interactions,
collisions, and reactions of ultracold molecules, that is, molecules having translational …

Magnetically tunable Feshbach resonances were employed to associate cold diatomic
molecules in a series of experiments involving both atomic Bose and two-spin-component …

Ultracold molecules offer unprecedented opportunities for the controlled interrogation of
molecular events, including chemical reactivity in the ultimate quantum regime. The …

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 …

The goal of the present article is to review the major developments that have led to the
current understanding of molecule–field interactions and experimental methods for …

We have converted an ultracold Fermi gas of L i 6 atoms into an ultracold gas of L i 2 6
molecules by adiabatic passage through a Feshbach resonance. Approximately 1.5× 10 5 …

It is shown that in the presence of inelastic scattering, zero energy elastic and inelastic
scattering can be characterized by a complex scattering length, the imaginary part of which …

Ultracold potassium molecules are produced in the X Σ g+ 1 electronic ground state by
photoassociation in a magneto-optical trap. They are detected sensitively and selectively by …

Ultracold collisions between Cs atoms and Cs 2 dimers in the electronic ground state are
observed in an optically trapped gas of atoms and molecules. The Cs 2 molecules are …

We present results of quantum mechanical scattering calculations including full rovibrational
coupling on the relaxation of vibrationally excited H 2 molecules in collision with ultracold 3 …
