TL;DR
The resonance properties of ultracold ground state Li, Li, and Na collisions are investigated using a modified version of Feshbach theory valid for strong fields and rigorous coupled-channel calculations.
Abstract
We investigate the resonance properties of ultracold ground state $^{6}\mathrm{Li}$${+}^{6}$Li, $^{7}\mathrm{Li}$${+}^{7}$Li, and $^{23}\mathrm{Na}$${+}^{23}$Na collisions. The locations of various resonances and their corresponding error bounds due to the uncertainty of the interatomic potentials are presented. Also, the resonance widths are computed using rigorous coupled-channel calculations, as well as a modified version of Feshbach theory valid for strong fields.

In all calculated elastic and inelastic two-body rates, a pronounced resonance structure is found, which can be understood in terms of the interplay between the singlet-triplet interaction and the hyperfine, Zeeman, and magnetic dipole interactions.

This type of trap has certain advantages for achieving the conditions for Bose-Einstein condensation in hydrogen or the alkalis, because it can confine atoms predominantly in the lowest energy spin state.

It is shown that polarization-gradient cooling occurs in the Ensuremath Lambda system, simultaneously with velocity-selective coherent population trapping (VSCPT), and may enhance the rate of three-dimensional VSCPT by 200 times over the rate achievable from Doppler precooling alone.
