While ultracold three-body recombination of bosons has been theoretically studied [1] because of its importance for Bose-Einstein condensates, similar studies have not been carried out for ultracold recombination of fermions. We will present the first such studies, examining the behavior of the recombination rate as a function of the p-wave scattering length [2] and comparing it with what is known about boson recombination. Implications for the many ongoing degenerate Fermi gas experiments [3] will also be discussed.
