Multiconfiguration multichannel Schwinger study of the C(1s) photoionization of CO including shake-up satellites. Academic Article uri icon


  • Often the inclusion of electron-correlation effects in photoionization calculations is crucial; e.g., calculation of satellite cross sections and asymmetry parameters in core ionization of molecules. We have developed a computational approach to include the relaxation, multiconfiguration, and multichannel effects, in a multichannel configuration-interaction (MCCI) approximation, for the study of molecular photoionization. Results are presented of a detailed MCCI-Schwinger study of the C(1s) core-hole production in CO, including the formation of the lowest two * shake-up satellites. It is shown that the multichannel effects are more important in describing the satellites than the core-hole channel. 1993 The American Physical Society.
