Abstract : The photoionization cross sections for the production of Xe(+), Xe(++), and Xe(+++), were measured in the energy range 28 to 83 eV. At energies between the thresholds for Xe(++) production, 33.3 eV, and 4d-electron removal, 67.55 eV, the Xe(++) cross section reaches about one-third of the total cross section. This cannot be accounted for by an independent electron model in terms of an electron shake-off process. At energies greater than 67.55 eV both the Xe(+) and Xe(++) cross sections increase; here the singly charged ion should be accompanied by fluorescence and the doubly charged ion can result from a simple Auger process. The triple ionization is attributed to a process which involves first the removal of a 4d-electron and then an Auger event in which two electrons are emitted simultaneously. (Author)
