Description
In this talk, I will present an experimental toolbox for selectively varying the contributions to the binding in long-range Rydberg molecules (LRMs). By studying photoassociation of heteronuclear LRMs in a dual-species MOT of $^{39}$K and $^{133}$Cs atoms, we explore the role of the $p$-wave scattering and hyperfine interaction to the binding energy and stability of LRMs. Millimeter-wave spectroscopy allows us to probe the bond length and electronic character. This work paves the way to a rigorous test of theoretical models, a prerequisite for the extraction of accurate low-energy electron scattering phase shifts from experimentally observed binding energies.
