Rydberg atoms in external electric and magnetic fields have recently emerged as atomic-scale laboratories where the quantum mechanics of classically nonintegrable systems can be studied. In this article we show, using classical canonical perturbation theory, how the intricate nonlinear dynamics of a Rydberg electron in crossed electric and magnetic fields can be described in terms of two coupled asymmetric tops.

We discuss high resolution spectroscopy experiments, currently being performed at our laboratories, on Rydberg atoms in crossed electric and magnetic fields in the context of the work carried out by Pierre Jacquinot and co-workers on Rydberg states of field-free atoms and atoms in external electric fields.
