Cs 62 D J Rydberg-atom macrodimers formed by long-range multipole interaction

Xiaoxuan Han, Suying Bai, Yuechun Jiao +5 more

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 molecules are measured by extraction of autoionization products and Rydberg-atom electric-field ionization, and ion detection. Molecular spectra are compared with calculations of adiabatic molecular potentials. From the dependence of the molecular signal on the detection delay time, the lifetime of the molecules is estimated to be $3--6\phantom{\rule{0.28em}{0ex}}\ensuremath{\mu}\mathrm{s}$.Long-range macrodimers formed by $D$-state cesium Rydberg atoms are studied in experiments and calculations.

High-resolution spectroscopy of Rydberg molecular states of Rb285 near the 5s+7p asymptote

Ryan Carollo, J. L. Carini, Edward E. Eyler +2 more

Rydberg molecules, often exemplified by long-range ``trilobite'' molecules, are a subject of much recent interest at high principal quantum number $n$ . States that use the same bonding mechanism can exist at much lower $n$ and less-extreme internuclear separations that are still quite long range. We use a high-resolution pulsed amplifier to study previously detected transitions to a low- $n$ Rydberg molecular state near the $5s+7p$ asymptote in $^{85}\mathrm{Rb}_{2}$ . The observed line structure is modeled using precise ground-state positions and a lower bound of $\ensuremath{\tau}>1.1\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}9}$ s is set on the excited-state autoionization lifetime.Rydberg molecules, often exemplified by long-range ``trilobite'' molecules, are a subject of much recent interest at high principal quantum number $n$.
