Observation of $\Pi$-symmetry ultralong-range Rydberg molecules

Matthew T. Eiles, Aleksandr Zaitsev, Dominik Dorer +5

We observe weakly-bound $\Pi$-symmetry electronic states in the spectroscopy of ${}^{87}$Rb$(n{P}_{3/2})$+${}^{87}$Rb($5S_{1/2}$) ultralong-range Rydberg molecules. We detect these molecul…
