采用 (1+1) 维模型，我们讨论了描述脉冲强微波场高激发氢原子电离的非微扰方法。我们将注意力限制在高尺度频率 n3ω≧1 上，并表明最近开发的 Landau-Zener 动力学图像可以透明地解释 Koch 等人测量的 10% 电离曲线中的突出结构。在使用微波腔的实验中；预计这些结构将以系统的方式依赖于边缘场参数。波导实验预计会产生性质不同的结果。
Employing a (1+1)-dimensional model, we discuss non-perturbative methods for the description of the ionization of highly excited hydrogen atoms by a pulsed strong microwave field. We restrict our attention to high scaled frequenciesn3ω≧1 and show that the recently developed picture of Landau-Zener dynamics leads to a transparent explanation of prominent structures in the 10% ionization curve measured by Koch et al. in experiments using microwave cavities; these structures are predicted to depend on fringe field parameters in a systematic manner. Waveguide experiments are expected to yield qualitatively different results.
