The L-shell internal-ionization probability accompanying K capture, K-shell internal-ionization probability accompanying L capture, and the ejected-electron spectrum during these processes have been calculated using screened relativistic hydrogenic wave functions. The screening constant for the daughter atom is determined taking into account the presence of a vacancy resulting from electron capture. The results show that L-shell contributions are important for the low-energy region of the electron spectrum and for high -Z elements. It is also concluded that the presence of a vacancy in the inner shell of the daughter atom plays an important role.
