Long-Lived Ultracold Molecules with Electric and Magnetic Dipole Moments

Abstract

We create fermionic dipolar ${}^{23}$Na${}^6$Li molecules in their triplet ground state from an ultracold mixture of ${}^{23}$Na and ${}^6$Li. Using magneto-association across a narrow Feshbach resonance followed by a two-photon STIRAP transfer to the triplet ground state, we produce $3\times 10^4$ ground state molecules in a spin-polarized state. We observe a lifetime of $4.6\text{s}$ in an isolated molecular sample, approaching the $p$-wave universal rate limit. Electron spin resonance spectroscopy of the triplet state was used to determine the hyperfine structure of this previously unobserved molecular state.
