这是第一个两篇论文，发展理论的振荡谱。当一个原子被放置在磁场中，并在有限的分辨率下测量到接近电离阈值的状态的吸收光谱，使得单个能级不能分辨时，发现吸收作为能量的函数是正弦振荡的叠加。这些论文提出了这种现象的定量理论。在这第一篇论文中，我们以最简单的方式描述了该理论的物理思想，并提出了基于该理论的第一次计算。在第二篇论文中，详细阐述了该理论，给出了所有断言的证明，并描述了用于计算的算法。
This is the first of two papers that develop the theory of oscillatory spectra. When an atom is placed in a magnetic field, and the absorption spectrum into states close to the ionization threshold is measured at finite resolution, so that individual energy levels are not resolved, it is found that the absorption as a function of energy is a superposition of sinusoidal oscillations. These papers present a quantitative theory of this phenomenon. In this first paper, we describe the physical ideas underlying the theory in the simplest possible way, and we present our first calculations based upon the theory. In the second paper, the theory is developed in full detail, proofs of all of the assertions are given, and we describe the algorithm that was used to make the calculations.
