With the advent of high-intensity lasers multiphoton ionization (MP I) processes have attracted considerable interest experimentally as well as theoretically. The study of the angular distribution of ejected photoelectrons yields information about the target atomic or molecular structure, as well as the various ionization channels involved.1 As has been found experimentally, measurements of the dependence of the MPI signal on the laser intensity deviate considerably from perturbation theory for laser intensities greater than 1013 W/cm2.2
