We study the van der Waals interaction between Rydberg alkali-metal atoms with fine structure ($n^2L_j$; $L\leq 2$) and heteronuclear alkali-metal dimers in the ground rovibrational state ($X^1\Sigma^+$; $v=0$, $J=0$). We compute the associated $C_6$ dispersion coefficients of atom-molecule pairs involving $^{133}$Cs and $^{85}$Rb atoms interacting with KRb, LiCs, LiRb, and RbCs molecules. The obtained dispersion coefficients can be accurately fitted to a state-dependent polynomial $O(n^7… 1 Citations ## Figures and Tables from this paper Strong zero-field Förster resonances in K-Rb Rydberg systems • Physics • 2020 We study resonant dipole-dipole coupling and the associated van der Waals energy shifts in Rydberg excited atomic rubidium and potassium and investigate Forster resonances between interspecies pair ## References SHOWING 1-10 OF 68 REFERENCES Short-range photoassociation of LiRb • Physics • 2016 We have observed short-range photoassociation of LiRb to the two lowest vibrational states of the$d\,^3\Pi$potential.
