Photoionization Cross Sections of Kr and Xe from Threshold up to 1000 eV
- Conference date: 24-28 June 2002
- Location: Rome (Italy)
Updated recommended data for absolute photoionization cross sections of Kr and Xe with uncertainties of ± 3 % are presented. The data are the result of a comprehensive analysis of reliable experimental measurements in absolute terms taking preceding recommendations into account. Significant corrections of the cross section values for certain photon‐energy regimes have been derived from the comparison of gas ionization by photons and electrons using a new experimental approach. The values presented serve as a background for new techniques to be used for the quantitative characterization of VUV‐FEL photon beams.
