Abstract

We have observed three Feshbach resonances in collisions between ⁶Li and ²³Na atoms. The resonances were identified as narrow loss features when the magnetic field was varied. The molecular states causing these resonances have been identified, and additional ⁶Li\mathrm\text\ensuremath-²³Na resonances are predicted. These resonances will allow the study of degenerate Bose-Fermi mixtures with adjustable interactions and could be used to generate ultracold heteronuclear molecules.
