Abstract

We have measured the alignment A20 of Xe+ ions after L3 photoionization via the anisotropy of L x-radiation using linearly polarized synchrotron radiation with energies of 4.814 and 5.055 keV, i.e. 27 and 268 eV above the L3 ionization energy, respectively. The alignment values are -0.061(43) and -0.044(70) for the respective photon energies. The experimental values are smaller in magnitude by roughly a factor of 2–3 than the theoretical ones which have been calculated for an extended energy range of photons within the Hartree–Fock approximation.
