    Comparisons of approximate bases for hydrogen in a magnetic field
    (American Physical Society, 1983) Zimmerman, Myron L.; Hulet, Randall G.; Kleppner, Daniel
    Solutions to the diamagnetic Hamiltonian for Rydberg states of hydrogen are studied in the low-magnetic-field regime where term mixing can be ignored. Several recently proposed approximate bases are compared by calculating the overlap integrals with an accurate numerically generated basis.

    Origin and Structure of the Quasi-Landau Resonances
    (American Physical Society, 1980) Castro, Jarbas C.; Zimmerman, Myron L.; Hulet, Randall G.; Kleppner, Daniel; Freeman, Richard R.
    Highly resolved spectra are presented which show how the low-magnetic-field energy-level structure of a single-electron atom gives rise to the quasi-Landau resonances as the field is increased. Data from the strong-mixing region where electric and magnetic forces are comparable reveal that evenly spaced energy levels are a general feature, irrespective of parity and magnetic quantum number of the states. The quasi-Landau resonances emerge by a concentration of oscillator strength into a single level of each term.
