Abstract
We create fermionic dipolar molecules in their triplet ground state from an ultracold mixture of and . Using magnetoassociation across a narrow Feshbach resonance followed by a two-photon stimulated Raman adiabatic passage to the triplet ground state, we produce ground state molecules in a spin-polarized state. We observe a lifetime of 4.6 s in an isolated molecular sample, approaching the -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.

A New Spin on Ultracold Molecules
Published 2 October 2017
The creation of ultracold molecules that have both an electric and a magnetic dipole moment offers new ways to explore physics in the many-body quantum regime.
