Precision Spectroscopy of the Fine and Hyperfine Structures of High Molecular Rydberg-Stark States: Metrology of Molecular Hydrogen Ions
{{output}}
The Stark effect in autoionizing high-n Rydberg states decouples the Rydberg electron from the ion core through ℓ mixing with core-nonpenetrating high-ℓ states. The Rydberg states become long-lived, which is ideal for precision spectroscopy, and their struct... ...
