Magnetically tuneable scattering resonance states have now been used to make cold diatomic molecules from two cold atoms in quantum degenerate Bose and Fermi gases. This talk will describe the basic properties of such resonance states for several atomic species and give a simple curve crossing model for understanding the atom-to-molecule conversion efficiency.
