Molecular and Rydberg physics have separately enjoyed, in the last decade or so, an enormous expansion due to the application of laser cooling techniques that allow control and resolution previously unattainable. One feld that lies at the intersection has not yet bene?ted from this development: heavy Rydberg states. In this experimental work, I investigated the possibility of ion pair production in ultracold rubidium through confguration mixing.

We propose a realizable and efficient approach for exciting long-range ion-pair molecules, known as heavy Rydberg states, in an ultracold ${}^{85}$ Rb gas via Feshbach resonances. Heavy Rydberg states, the molecular analogs of electronic Rydberg states, with the electron replaced by an atomic anion, offer opportunities for novel physics, including the formation of ultracold anions and strongly coupled plasmas. We map the positions, lifetimes, and Franck-Condon factors of heavy Rydberg resonances across a wide range of excitation energies, and we calculate the rates of formation for the most promising transitions through long-lived intermediate interferometric resonances.We propose a realizable and efficient approach for exciting long-range ion-pair molecules, known as heavy Rydberg states, in an ultracold ${}^{85}$Rb gas via Feshbach resonances.
