Spectroscopy of ultracold trapped cesium Feshbach molecules
We explore the rich internal structure of ${\text{Cs}}_{2}$ Feshbach molecules. Pure ultracold molecular samples are prepared in a ${\text{CO}}_{2}$-laser trap, and a multitude of weakly bound states is populated by elaborate magnetic-field ramping techniques. Our methods use different Feshbach resonances as input ports and various internal level crossings for controlled …
