Abstract
We demonstrate that we can use the extreme ultraviolet radiation produ ced by high order harmonic generation to perform photoionization exper iments. With harmonics from the 11th to the 69th of a 140 fs Cr:LiSAF laser operating at 825 nm, we measure the relative photoionization cro ss sections of xenon, krypton, argon and neon over the range 10 to 110 eV. With narrow bandwidth harmonics produced by a tunable, 1 ps dye l aser, we observe the autoionizing states between the 4p(5) ionization thresholds in krypton.
