Magnetic Feshbach resonances in Ba${}^{+}$+Li collisions due to strong spin-orbit coupling

Masato Morita, Joachim Siemund, Wei Wu +8

We report a pronounced dependence of magnetic Feshbach resonance spectra on the initial hyperfine-Zeeman state of Li in ultracold ${}^{138}$Ba${}^{+}$+${}^6$Li collisions. The measured num…
