Long-range macrodimers formed by $D$-state cesium Rydberg atoms are studied in experiments and calculations. Cesium ${[62{D}_{J}]}_{2}$ Rydberg-atom macrodimers, bonded via long-range multipole interaction, are prepared by two-color photoassociation in a cesium atom trap. The first color (pulse A) resonantly excites seed Rydberg atoms, while the second (pulse B, detuned by the molecular binding energy) resonantly excites the Rydberg-atom macrodimers below the ${[62{D}_{J}]}_{2}$ asymptotes. The…

Observation of ultralong-range Rydberg molecules

The spectra of the vibrational ground state and of the first excited state of the Rydberg molecule, the rubidium dimer Rb(5s)–Rb(ns), agree well with simple model predictions and allow us to extract the s-wave scattering length for scattering between the R Sydberg electron and the ground-state atom, Rb (5s), in the low-energy regime.

Observation of Rydberg-Atom Macrodimers: Micrometer-Sized Diatomic Molecules.

It is shown that a full model is required to accurately predict the occurrence of bound Rydberg macrodimers, which are distinguished from repulsive molecular states by their behavior with respect to spontaneous ionization and possible decay channels.
