Weakly bound dimers of fermionic atoms
arXiv:cond-mat/0309010 · doi:10.1103/PhysRevLett.93.090404
Abstract
We discuss the behavior of weakly bound bosonic dimers formed in a cold Fermi gas at a large positive scattering length for the interspecies interaction. We find the exact solution for the dimer-dimer elastic scattering and obtain a strong decrease of their collisional relaxation and decay with increasing . The large ratio of the elastic to inelastic rate is promising for achieving Bose-Einstein condensation of the dimers and cooling the condensed gas to very low temperatures.
