Rydberg molecules formed by the low-energy scatter-ing of a Rydberg electron and a ground-state atom con-stitute a distinct class of molecular states that have inrecent years become the subject of signi cant theoret-ical and experimental interest. Developments includestudies of diatomic Rydberg molecules in low-angular-momentum Rydberg S-states [1, 2], P-states [3], and D-states [4, 5], the realization of coherent bonding and dis-sociation of S-type molecules [6], and the rst observationof a permanent electric dipole moment in a homonuclearmolecule [7]. Polyatomic Rydberg molecules have alsobeen generated [8] and employed in a demonstration ofthe continuous transition between a few-body to many-body regime in an ultracold quantum gas [9].The theoretical framework for these molecules is gen-erally well-established. The interaction between a low-energy Rydberg electron and ground-state atom can bedescribed using a Fermi pseudo-potential approach [10{12]. In the Fermi model, the ground-state atom is treatedas a delta-function perturber of the Rydberg-electronwave function, resulting in oscillatory potential curveswith localized minima capable of sustaining bound molec-ular states. In alkali systems, the potential curves arestrongly a ected by low-energy
