R. Gebarowski et J. Zakrzewski, IONIZATION OF H-RYDBERG ATOMS BY MICROWAVES - PULSE-SHAPE INFLUENCE ON THE ALGEBRAIC DECAY, Physical review. A, 50(5), 1994, pp. 4408-4411
A classical study is performed of the ionization of hydrogen Rydberg a
toms by circularly polarized microwaves. It is shown that the electron
survival probability may decay algebraically for long microwave pulse
s. The character of the decay is sensitive to the initial atomic state
as well as to the assumed shape of the microwave pulse.
