| 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. |
