Abstract
A simple method for the determination of saturation intensities and in some cases generalized cross sections in multiphoton ionization is pr esented. It utilizes the dependence of the ponderomotive shift on the laser intensity above the saturation limit. An application to He Ar in teracting with 500 fs pulses at 248 nm is demonstrated. Experimental r esults are compared with theoretical calculations.
