The intensity dependence of the multiphoton ionization spectra of Xenon atoms has been investigated with an improved accuracy and well controlled laser parameters. In particular, we have examined the ionization rates for Xe3+, Xe2+, X+ as functions of the laser intensity and gas pressure in the target chamber. The apparatus used for these measurements is characterized by a high energy resolution and a completely digital acquisition system. The ionization rates of the different ions have been used for testing the basic assumptions of the Geltman theory of multiple ionization based on the single electron ionization model.
