Аннотация
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.
