Heavy Rydberg states: large amplitude vibrations

Abstract

Extremely large vibrational amplitude (≈ 8700 a.u.) heavy Rydberg levels in the HHbar 1Σ+g state, located only 25 cm−1 below the ion-pair dissociation limit, are reported. The calculations are done using a hybrid log derivative - multichannel quantum defect approach capable of dealing with any number of long-range closed channels, and provides line positions and widths. In this instance, the pattern of line positions can be reproduced qualitatively using a simple diabatic model (however, the line widths can not). Absolute quantum defects are derived for the vibrational series ranging from ν = 0 to ν = 2010. The influence of the Coulomb potential and continuity of heavy Rydberg behavior throughout the 1Σ+g manifold of states is demonstrated.
