By solving the time-dependent Schrodinger equation nonperturbatively by the state-specific expansion approach, we have obtained reliable results showing the dependence of the formation of the excitation profile of the autoionizing state He '2s2p'(1)P(o) for Gaussian pulses of intensities in the range I approximate to 10(10) W/cm(2) to I approximate to 10(15) W/cm(2), and of duration 100-2 fs. Conclusions are drawn as regards the breakdown of first-order time-dependent perturbation theory.
