Photoionization of Xe and Rn from the relativistic random-phase theory

Photoionization cross section $sigma_{nkappa}$, asymmetry parameter $beta_{nkappa}$, and polarization parameters $xi_{nkappa}$, $eta_{nkappa}$, $zeta_{nkappa}$ of Xe and Rn are calculated in the fully relativistic formalism. To deal with the relativistic and correlation effects, we adopt the relativistic random-phase theory with channel couplings among different subshells. Energy ranges for giant emph{d}-resonance regions are especially considered.
