Recombination of three ultracold fermionic atoms

By H. Suno, B. D. Esry and Chris H. Greene


Three-body recombination of identical, spin-polarized fermionic atoms in the ultracold limit is investigated. The mechanisms for recombination are described in terms of the ``scattering volume'' $V_p$ in the framework of the adiabatic hyperspherical representation. We have calculated numerically the recombination rate $K_3$ as a function of $V_p$ and have found that $K_3$ scales as $|V_p|^{8/3}$ for small $|V_p|$. A comparison with experimental data is also presented.Comment: 4 pages, 3 figure
