Abstract

In this work photoionization cross sections have been measured in xenon and oxygen. In Xe, cross sections at 248 and 193 nm from the 5p56p J= 0,J = 2 states at 80119 and 79213 cm−1, respectively, were measured. The excited atoms were prepared by nonresonant two-photon absorption from the ground state, and the fluorescence decay to the 5p56s configuration was observed. Shortly after the end of this first laser pulse a second ionizing laser pulse impinges on the excited atoms, depleting the fluorescence.
