Abstract
The microwave ionization of internally chaotic Rydberg atoms is studied ana lytically and numerically. The internal chaos is induced by magnetic or sta tic electric fields. This leads to a chaotic enhancement of microwave excit ation. The dynamical localization theory gives a detailed description of th e excitation process even in a regime where up to few thousands photons are required to ionize one atom. Possible laboratory experiments are also disc ussed.
