Title: Landau Quantization and Time Dependence in the Ionization of Cold, Strongly Magnetized Rydberg Atoms

Abstract

The electric-field-ionization and autoionization behavior of cold Rydberg atoms of {sup 85}Rb in magnetic fields up to 6 T is investigated. Multiple ionization potentials and field-ionization bands reflecting the Landau energy quantization of the quasifree Rydberg electron are observed. The time-resolved and state-selective field-ionization study provides evidence of m mixing and spin flips of the Rydberg electron. Spin-orbit coupling combined with m mixing gives rise to a Feshbach-type autoionization of metastable positive-energy atoms.
