Experiments have shown that the microwave ionization probability of a highlyexcited almost monodimensional hydrogen atom subjected to a microwave pulsesometimes grows in steps when the peak electric field of the pulse isincreased. Classical pulsed simulations display the same steps, which have beentraced to phase-space metamorphoses. Quantum numerical calculations againexhibit the same ionization steps. I show that the time-sequence of two levelinteractions, responsible for the observed steps in the quantum picture, isstrictly related to the classical phase space structures generated by the abovementioned metamorphoses.
