Ultracold Ground-State Molecule Production in Sodium
F K. Fatemi, Kevin Jones, Paul D. Lett, Eite Tiesinga
We have observed the formation of ground state Na2 molecules via the spontaneous decay of excited molecules created by the photoassociation of ultracold atoms. We measure the energies of ground state molecules formed in three hyperfine components of the Na2 a 3ς+u (v=15) state by two different methods. Two of the features are purely-triplet (quasi-bound) states that have not been previously observed. The molecules are detected with high-resolution cw laser ionization techniques and located to within 10 MHz.
