Observation of Collisions between Two Ultracold Ground-State CaF Molecules
Observation of Collisions between Two Ultracold Ground-State CaF Molecules
We measure inelastic collisions between ultracold CaF molecules by combining two optical tweezers, each containing a single molecule. We observe collisions between Σ2 CaF molecules in the absolute ground state |X,v=0,N=0,F=0⟩, and in excited hyperfine and rotational states. In the absolute ground state, we find a two-body loss rate of …
