We report an application of our previously developed model for determining the probabilities P-italic(..cap alpha../sub N-italic/,N-italic/sub A-italic/) of emitting N-italic/sub A-italic/ Auger electrons and the probabilities P-italic(..cap alpha../sub N-italic/,..beta../sub N-italic/..--> gamma../sub N/) of the radiative transitions ..beta../sub N-italic/..--> gamma../sub N/ during the cascade decay process following the creation of an arbitrary distribution ..cap alpha../sub N-italic/ of N-italic vacancies among the n-italicl-italic subshells of an atomic system. Particular emphasis has been given to the effects of single inner-shell vacancies, which may be created by energetic charged-particle collisions or by x-ray photoionization. Results of calculations are presented for single inner-shell electron ionization of iron ions from the neutral atom through the heliumlike ionization state, taking into account all of the Auger, Coster-Kronig, and electric dipole radiative transitions which can occur during the inner-shell vacancy-cascade process. The importance of the multiple ionization which results from Auger electron emission and of the x-ray satellite line radiation which is produced by the radiative decay of multiple-vacancy states is investigated for inner-shell electron ionization by electron collisions and by photon impacts.
