强场中的里德伯原子具有标度特性，可以根据经典轨迹详细解释光吸收光谱。如果在恒定的标度能量下获得谱，则经典动力学保持不变。由于每个在原子核处闭合的轨道在吸收光谱中产生正弦调制，它的特征是标度能谱的傅里叶变换中的一个峰。本文确定了在混沌刚刚开始发展的地区，在平行电场和磁场中氢原子的计算谱中闭合轨道的影响。
Rydberg atoms in strong fields have scaling properties that allow detailed interpretation of photoabsorption spectra in terms of classical trajectories. The classical dynamics remains invariant if a spectrum is obtained at constant scaled energy. Since each orbit which is closed at the nucleus produces a sinusoidal modulation in the absorption spectrum, its signature is a peak in the Fourier transform of a scaled-energy spectrum. This paper identifies the effect of closed orbits in the computed spectrum of the hydrogen atom in parallel electric and magnetic fields in a region where chaos is just beginning to develop.
