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

摘要

Partial photoionization cross sections from the 1 Sground and the3P 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.
