Interplay between relativistic energy corrections and resonant excitations in x-ray multiphoton ionization dynamics of Xe atoms

In this paper, we theoretically study x-ray multiphoton ionization dynamics of heavy atoms taking into account relativistic and resonance effects. When an atom is exposed to an intense x-ray pulse generated by an x-ray free-electron laser (XFEL), it is ionized to a highly charged ion via a sequence of single-photon ionization and accompanying relaxation processes, and its final charge state is limited by the last ionic state that can be ionized by a single-photon ionization. If x-ray multiphoton ionization involves deep inner-shell electrons in heavy atoms, energy shifts by relativistic effects play an important role in ionization dynamics, as pointed out in Phys. Rev. Lett. 110, 173005 (2013). On the other hand, if the x-ray beam has a broad energy bandwidth, the high-intensity x-ray pulse can drive resonant photoexcitations for a broad range of ionic states and ionize even beyond the direct one-photon ionization limit, as first proposed in Nat. Photon. 6, 858 (2012). To investigate both relativistic and resonance effects, we extend the XATOM toolkit to incorporate relativistic energy corrections and resonant excitations in x-ray multiphoton ionization dynamics calculations. Charge-state distributions are calculated for Xe atoms interacting with intense XFEL pulses at a photon energy of 1.5 keV and 5.5 keV, respectively. For both photon energies, we demonstrate that the role of resonant excitations in ionization dynamics is altered due to significant shifts of orbital energy levels by relativistic effects. Therefore, it is necessary to take into account both effects to accurately simulate multiphoton multiple ionization dynamics at high x-ray intensity.

“…The usefulness of this formula can be easily pointed out, since the reduced matrix element (JrllVllJr) is the well known matrix element which occurs for Auger transitions on elements with closed subshells such as Kr or Xe. These matrix elements are analysed by Asaad (1963) and have been calculated for several transitions (e.g. Kabachnik and Sazhina 1988, Lohmann 1988, Lohmann 1990, Kabachnik et al 1991.…”

A model is developed to calculate anisotropy coefficients for resonant Auger emissions and for normal Auger emissions on elements with one electron in an open subshell. By applying some simple restrictions to the model the author connects the required matrix elements with those for the case of closed subshells which are already analysed. For an intermediate state with Jf=0 the angular distribution becomes independent of the matrix elements. The angular distribution parameters are calculated for these cases.
