Abstract

The cross section for photoionization of Xe⁷⁺ has been measured on an absolute scale with the photon-ion merged beams technique at a synchrotron light source. The experimental photon energy range of 95 145 eV comprises the ground state ionization threshold at about 106 eV and the prominent 4d⁹ 5s 5f²P resonance at 122.14 o 0.2 eV. The strength of this resonance is found to account for 15% of the 4d absorption oscillator strength. With an experimental photon energy spread of 50 meV the 4d⁹ 5s 5f²P resonance width could be determined with 8% uncertainty to be 72 meV.
