3d photoionization along the xenon isoelectronic sequence

摘要: The relativistic time-dependent density functional theory has been applied to 3d photoionization along the Xe isoelectronic sequence, from I− La3+. It is seen that interchannel coupling between two spin–orbit channels greatly alters their partial cross sections. Changes similar those already observed for system are affect I−3d5/2 section. For elements following noble gas in Rydberg series of autoionization resonances associated with excitations into closed 3d3/2 → np1/2,3/2; n'f5/2 strongly modulate total and 3d5/2 sections split thresholds. Moreover, analysis transfer oscillator strength continuum discrete part spectrum permitted us follow occurrence collapse 4f wavefunction a hole, which occur Cs+. A global picture emerges comparison 4d ionization neutral systems series.
