给出了由碱金属原子里德堡态组成的波包的计算结果。我们证明了这种波包在极角和方位角中局部化是可能的。这个波包的演化相当于经典开普勒轨道在微扰势的影响下的进动。在这种情况下，微扰就是碱金属原子的量子亏损。提出了一种产生这些状态的激励方案，并给出了基于该方案的数值模型的结果。最后，讨论了这些角度局域波包与外场的相互作用，并提出了一种探测方法。
Calculations are presented that show the behavior of a wave packet composed of alkali-metal-atom Rydberg states. We demonstrate that it is possible to localize such a wave packet in the polar and azimuthal angles. The evolution of this wave packet is equivalent to the precession of a classical Kepler orbit under the influence of a perturbing potential. In this case, the perturbation is the quantum defect of the alkali-metal atoms. An excitation scheme is proposed for producing these states and the results of a numerical model based on this scheme are presented. Finally, the interaction of these angularly localized wave packets with external fields is discussed and a method of detection is suggested.
