Based on the principle of the photoelectron imaging spectrometry,taking sodium atoms as an example,the characters of the photoelectrons angular distribution and the interference effect ,which are produced from double-level of the D state of the atomic sodium,are investigated analytically by using the two-photon resonance and three-photon ionization.The energy and the space angular distribution of the photoelectrons are described expressly by the photoelectron imaging.The result for the analysis the photoelectrons angular distribution possesses significances.
