Ionization of hydrogen atoms with principal quantum number $n=32$, 40, and 51-74 by a 9.92-GHz electric field $\mathrm{F}(t)=\stackrel{^}{z}{F}_{0}cos\ensuremath{\omega}t$ was studied with a superimposed static electric field ${\overline{F}}_{s}=0, 2, 5, \mathrm{and} 8$ V/cm. The measured field strengths ${F}_{0}(10%)$ at which 10% of the atoms were ionized are in excellent agreement with classical calculations in both one and two spatial dimensions. Covering finer detail as well as gross structure of the $n$ dependence of ${F}_{0}(10%)$, the agreement supports the application of classical dynamics to the analysis of this strongly perturbed quantum system.
