Ionization Energies and Lifetime Broadening of Autoionizing States of the Hydrogen Atom in Strong Magnetic Fields: Theory vs. Experiment

Abstract
Theoretical results for the ionization energies of some autoionizing states of the hydrogen atom in magnetic fields up to 5105 T, as obtained by Friedrich et al. (Phys. Rev. A, 28 (1983) 1423) are compared for the first time with experimental data, derived from farinfrared magneto-optical experiments on shallow donors in n-GaAs. The theoretical calculations are found to give an excellent description of the experimental results in the reduced field range 0.15 < γ = ωcr/2 Ry < 1. Also predictions for the lifetime broadening of these states match the experimental data quite well.
