摘要：

基于光电子角分布成像光谱技术的基本原理，以钾原子为例，在理论上讨论单光子共振双光子电离方法获得的光电子成像光谱.光电子空间角分布与电离过程中的干涉作用有关,最后分析干涉图与原子能态信息的关系.

关键词: 光电子角分布；光电子干涉；双光子电离

Abstract:

Based on principle of photoelectron angular distribution imaging spectrometry, with potassium atoms as an example, the interference pattern of angular distributions of photoelectrons are obtained using a single photon resonant excitation and two-photon ionization. The angular distribution of photoelectrons is closely related to interference. The interference pattern and information of the atomic energy states are discussed in detail.

Key words: photoelectron angular distributions; photoelectron interference; two-photon ionizaton
