17. We use atomic units throughout.
18. We use an analytic expression for the energy gain, Eq. (5), which is adequate for circular polarization and, consequently, an unaveraged formula for the tunneling rate, Eq. (2). Corkum's simulations use the formula for ionization given by M. V. Ammosov, N. B. Delone, and V. P. Krainov, Zh. Eksp. Teor. Fiz. 91, 2008 (1986) [Sov. Phys. JETP 64, 1191 (1986)], i.e., the quasi-static tunneling formula averaged by the radiation cycle and, consistently, the rotating-wave approximation for the electron motion.

20. th for the final stage of ionization; however, the intermediate intensities can differ substantially. Our FMD simulations are closer to the second formula; however, the accuracy of the experiment is insufficient to permit us to distinguish between these versions of the OBI threshold.
