Deeply bound (24$D_J$ + 5$S_{1/2}$) ${}^{87}$Rb and ${}^{85}$Rb molecules for eight spin couplings

Jamie L. MacLennan, Yun-Jhih Chen, Georg Raithel

We observe long-range ${}^{85}$Rb and ${}^{87}$Rb (24$D$+5$S_{1/2}$) Rydberg molecules for eight different spin couplings, with binding energies up to 440~MHz and sub-percent relative…
