L-subshell state-to-state photoionization cross sections for the carbon isoelectronic sequence
The state-to-state photoionization cross sections for ionizing an L-subshell electron from the 1s/sup 2/2s/sup 2/2p/sup 2/ configuration of the carbonlike ions have been calculated for seven ions with atomic number 6less than or equal toZless than or equal to54 for the photon energy in the range 6less than or equal toEless than or equal to16 keV by using the newly developed multiconfiguration Dirac-Fock photoionization code. The calculations were performed in the intermediate coupling including the initial-state and final-ionic-state configuration interaction from the same complex. The spin-orbit interaction has been found to drastically alter the branching ratios for 10<45. For Zless than or equal to10, the branching ratios agree with the LSJ coupling limit while for Zgreater than or equal to45, the branching ratios approach the j-j coupling limit. The effects of relativity change the total cross section by an amount less than 14% for the Xe/sup 48+/ ion.
