Rydberg Series of Two-Electron Systems Studied by Hyperfine Interactions

摘要: For almost a decade, the study of atomic Rydberg states, i.e., states with one highly excited electron orbiting around an ion core, has been fascinating and actively pursued field physics.(1–3) Considerable experimental theoretical efforts have spent to elucidate electronic structure such states. Term values, fine splittings, lifetimes, or oscillator strengths, as well effect external fields, Zeeman Stark may be used probe change in occurring along series. Generally, these quantities vary regularly increasing effective principal quantum number n*. Deviations from expected trend indicative for perturbations structure. This situation is frequently encountered two-electron systems where configuration interactions lead dramatic changes within given
