Rydberg states in crossed fields: The gyropendulum
The spectrum of degenerate Rydberg states of an n-manifold of the hydrogen atom when placed in crossed (perpendicular) electric and magnetic fields (the diamagnetic term is disregarded) is shown to conicide with that of a charged-particle harmonic oscillator in a magnetic field. A mechanical counterpart is identified as the gyropendulum. These correspondences give further insight into the nature of Rydberg states in external fields. © 1986 The American Physical Society.
