Characterization of Feshbach resonances in ${}^6\mathrm{Li}{-}^7\mathrm{Li}$ using improved interaction potentials

Jing-Chen Zhang, Paul Julienne, Yu Liu

We characterize Feshbach resonances in all isotopologues of the $\mathrm{Li}-\mathrm{Li}$ system with improved interaction potentials. Starting from spectroscopically accurate Mo…
