cannot be explained correctly.

If the rate into 23-dimers could be separated experimentally from the total rate, it would clearly determine the positions of the local minima. This could be achieved by tuning the depth of trapping potential such that it is much larger than the kinetic energies of atoms and 23-dimers in the final state but much smaller than the energies of atoms and deep dimers in the final state. The kinetic energies of an atom and a deep dimer in the final state could be estimated from the binding energy of the deep dimers. Their energies would be of the order of the van der Waals energy or larger: $E_{\rm vdW}/h
\approx 154$ MHz, where $E_{\rm vdW}=\hbar^2/(m\ell_{\rm vdW}^2)$.[^1] The kinetic energies of an atom and a 23-dimer are given by the difference in binding energies between the 12-dimer and the 23-dimer: $\hbar/(2\pi m)(a_{23}^{-2}-a_{12}^{-2})$ is about $1$ MHz at 650 G and vanishes at 730 G. This way one may be able to measure the rate into deep dimers separately and to extract the rate into the 23-dimer.

Finite Temperature Results {#sec:themal}
==========================

The results from the previous section suggest that finite temperature effects may play an important role
