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

Abstract

Photoionization cross section $\ddot{I}{ƒ}_{n\hat{I}º}$, asymmetry parameter ${\hat{I}}_{n\hat{I}º}^2$, and polarization parameters $\hat{I}{¾}_{n\hat{I}º}$, $\hat{I}{\cdot }_{n\hat{I}º}$, $\hat{I}{\P }_{n\hat{I}º}$ 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.
