Heavy polar molecules like BaF are key to boosting measurement sensitivity of the electron’s electric dipole moment (eEDM), but slowing heavy molecules to near-zero velocity for experiments is challenging. This study achieved reducing BaF’s total leakage fraction to 10−5 using microwave remixing and optical pumping and slowing buffer-gas-cooled BaF molecules from ~ 80 m/s to near-zero velocity.
