Formation of Quantum-Degenerate Sodium Molecules
Formation of Quantum-Degenerate Sodium Molecules
Ultracold sodium molecules were produced from an atomic Bose-Einstein condensate by ramping an applied magnetic field across a Feshbach resonance. More than ${10}^{5}$ molecules were generated with a conversion efficiency of $\ensuremath{\sim}4%$. Using laser light resonant with an atomic transition, the remaining atoms could be selectively removed, preventing fast collisional …
