Abstract

We have investigated magnetically tunable Feshbach resonances arising from the interaction of Li(²S) with metastable Yb(³P₂) and (³P₀). For Yb(³P₂), all the resonance features are strongly suppressed by inelastic collisions that produce Yb in its lower-lying ³P₁ and ³P₀ states. For Yb(³P₀), sharp resonances exist but they are extremely narrow (widths less than 1 mG).
