Abstract
Based on our generalized Keldysh theory [K. Mishima et al. : Phys. Rev. A 66 (2002) 033401], we derive a compact rate formula for tunneling photo-ionization rates of one-electron atoms. Our total ionization rate does not contain any series-summation or integral and thus is as simple as the Ammosov–Delone–Krainov ionization rate. In addition to its simplicity, our formula can explicitly show the wavelength dependence of the ionization rates. Furthermore, a simple form of the differential ionization rate is available.
