Interference oscillations in ionization of extreme Stark states by half-cycle pulses

We study the classical, semiclassical, and quantum dynamics of parabolic Rydberg states of hydrogen subject to half-cycle electromagnetic pulses as a function of the field strength and the duration of the pulses. We show that for the most ``red-shifted`` Stark state the quantum ionization probability oscillates around the classical value. These oscillations can be described semiclassically in terms of path interference. By contrast, the ionization probability of the extreme ``blue-shifted`` state is a smooth function of field strength. These predictions could be tested experimentally.
