Mini-Symposium: Spectroscopic Perturbations
Scientific paper
As a step towards measuring the electron electric dipole moment, we produce a sample of HfF^+ using a two-color excitation. We promote HfF from X^2 Δ3/2 to an isotope and parity-selective intermediate state, and then to one of many highly perturbed Rydberg states from which it autoionizes to the vibrational ground state of HfF^+. We measure the population of the rotational states of HfF^+ using laser-induced fluorescence and find that only a small number of states are populated, with most of the population in J < 4. Additionally, we see a strong propensity for autoionization to preserve the parity of the molecule, with one parity populating even J levels and the other populating odd J. Using polarized light to prepare the Rydberg molecules in various orientations, and then probing the ion with LIF, we see that a polarization of m_J sublevels also survives autoionization.
