Scattering properties of weakly bound dimers of fermionic atoms

ORAL

Abstract

We discuss the behavior of weakly bound homonuclear and heteronuclear bosonic molecules formed in a two-component Fermi gas with a large positive scattering length for the interspecies interaction. We present a theoretical approach for solving a few-body scattering problem and describe the physics of dimer-dimer elastic and inelastic scattering. We explain why these diatomic molecules, while in the highest ro-vibrational level, are characterized by remarkable collisional stability.
