Screening effects in multielectron ionization of heavy atoms in intense laser fields
Summary, in English
Multielectron ionization of Xe is described in terms of multistep processes, driven by a laser field which is screened by the motion of the outer 5p shell. In stepwise multiple ionization of the 5p shell, screening is successively reduced. The effective, local intensity will therefore increase during the stripping of the outer shell. In the 4d inner-shell region the effective intensity is very low. Finally we point out difficulties connected with the tentative identification of recently observed 4d Auger spectra.
