Theoretical and Expert System Study of the Photoionization Theories

Attempts are made to analyze the influence of ponderomotive and Stark shifts on the tunneling transition rate for alkali and noble atoms for a non relativistic linearly polarized laser field. Three theories: Keldysh, PPT and the ADK are considered in this paper. It is shown that the ponderomotive an...

Zusammenfassung:Attempts are made to analyze the influence of ponderomotive and Stark shifts on the tunneling transition rate for alkali and noble atoms for a non relativistic linearly polarized laser field. Three theories: Keldysh, PPT and the ADK are considered in this paper. It is shown that the ponderomotive and Stark shifts affect the rate and differently for different approaches. Obtained results are discussed for the different laser beam shapes. Finally, a expert system is presented for analysis of photoionization theories.
