Satellite lines in the photoionization of ions: The Be isoelectronic sequence

TL;DR

This paper investigates satellite lines in the photoionization of ions in the Be isoelectronic sequence, analyzing how their cross sections vary with atomic number and photon energy using the R-matrix method.

Contribution

It provides detailed calculations of satellite partial cross sections for the Be isoelectronic series, revealing their monotonic decrease with atomic number and complex energy dependence.

Findings

Satellite cross section ratios decrease monotonically with Z.

Complex energy-dependent patterns of satellite ratios are identified.

The R-matrix method effectively models photoionization processes.

Abstract

Partial photoionization cross sections from the ^1S ground and the ^3P metastable states of the Be isoelectronic series to different final states including a number of satellite (ionization plus excitation) channels are studied using the R-matrix method. As expected, the ratio of each satellite partial cross section to the dominant partial cross section is found to be a monotonic decreasing function of Z for both the ground and the metastable states. The complicated patterns of these ratios as functions of photon energy are analyzed.
