Comparison of the Xe/sup +/ data with 4d partial photoionization cross-section measurements indicates the important role played by many-body effects in describing electron-impact ionization of high-Z atoms.Abstract:
High-sensitivity measurements of relative partial cross sections for single, double, and triple ionization of Xe by electron impact have been carried out in the energy region from threshold to 100 eV using a crossed-beam apparatus incorporating a quadrupole mass spectrometer. The weighted sum of the relative partial cross sections at 50 eV are normalized to the total ionization cross section of Rapp and Englander-Golden to yield absolute cross-section functions. Shapes of the partial cross sections for single and double ionization are difficult to account for within a single-particle picture. Comparison of the ${\mathrm{Xe}}^{+}$ data with 4d partial photoionization cross-section measurements indicates the important role played by many-body effects in describing electron-impact ionization of high-Z atoms.read more

Evidence for coherent electron motions in multiphoton X-ray production from Kr and Xe clusters
TL;DR: In this paper, three generalizations of the original formulation of the interaction were necessary to reconcile theoretical estimates with these experimental findings, including an enhancement in the coupling arising from the coherent motion of the (Z) field ionized electrons induced by the external driving field.

Impact of interatomic electronic decay processes on Xe 4d hole decay in the xenon fluorides
TL;DR: In this paper, the authors derived a relation between two-hole population numbers and partial Auger widths and showed that interatomic electronic decay processes are so strong in the xenon fluorides that they overcompensate the reduction in intra-atomic Augerwidth and lead to the experimentally observed trend.
