- Title: Heteronuclear long-range Rydberg molecules
- Authors: Michael Peper and Johannes Deiglmayr
- Abstract summary: We present the formation of homonuclear Cs2, K2, and heteronuclear CsK long-range Rydberg molecules in a dual-species magneto-optical trap for 39K and 133Cs by one-photon UV photoassociation.
The different ground-state-density dependence of homo- and heteronuclear photoassociation rates and the detection of stable molecular ions resulting from auto-ionization provide an unambiguous assignment.

- Abstract: We present the formation of homonuclear Cs2, K2, and heteronuclear CsK
long-range Rydberg molecules in a dual-species magneto-optical trap for 39K and
133Cs by one-photon UV photoassociation. The different ground-state-density
dependence of homo- and heteronuclear photoassociation rates and the detection
of stable molecular ions resulting from auto-ionization provide an unambiguous
assignment. We perform bound-bound millimeter-wave spectroscopy of long-range
Rydberg molecules to access molecular states not accessible by one-photon
photoassociation. Calculations based on the most recent theoretical model and
atomic parameters do not reproduce the full set of data from homo- and
heteronuclear long-range Rydberg molecules consistently. This shows that
photoassociation and millimeter-wave spectroscopy of heteronuclear long-range
Rydberg molecules provide a benchmark for the development of theoretical
models.

ionic products, created by the decay of a long-range Rydberg molecule, modify the excitation spectrum of surrounding ground-state atoms.
Pulsed-field ionisation typically doesn't discriminate between the ionization of a long-range Rydberg molecule and an isolated Rydberg atom.
We unambiguously identify the signatures of this detection mechanism in the photoassociation of long-range Rydberg molecules bound below nP_3/2 Rydberg states of cesium.
