THE EFFECTS OF SECOND-ORDER IONIZATION PROCESSES ON THE PHOTOELECTRON SPECTRUM OF TWOPHOTON AUTOIONIZATION
二阶离化过程对双光子自电离光电子能谱的影响

In this paper, the two-photon autoionization involving second-order ionization processes is investigated. The photoelectron spectra are calculated, and the effects of second-order process on the photoelectron spectra and the relation of spectra's variation with intensity of light are emphatically analyzed.
