We have calculated, by numerically integrating the time-dependent Schroedinger equation, the probability for ionization of a hydrogen atom from a high Rydberg state by a half-cycle pulse whose duration is comparable to, or shorter than, the period of the Rydberg orbit. We have chosen a pulse whose parameters are the same as the pulse used in the experiment of R. R. Jones, D. You, and P. H. Bucksbaum [Phys. Rev. Lett. 70, 1236 (1993)]. We compare our results with the classical results and with the experimental data of Jones [ital et] [ital al]., and we also present results for energy and angular distributions. Finally, we derive an approximate conservation law which applies in the limit of very short pulse times.
