Classical Thresholds for H Atom Ionization by Circularly Polarized Microwave Fields.
Krzysztof Sacha, Robert Gebarowski and Jakub Zakrzewski

Ionization of H atoms by circularly polarized microwaves is studied within the classical mechanics framework. We compare recent predictions coming from the Chirikov overlap criterion with results of numerical simulations for finite interaction time. The numerical threshold dependence on the interaction time is shown to obey a power law behaviour for high frequencies.
