Shake-up satellites accompanying the inner shell ionization of alkali atoms

The shake-up probabilities of the outermost electron in inner shell ionization and subsequent Auger decay of alkali atoms have been studied in the sudden approximation model using the wavefunctions obtained with the multiconfiguration Dirac-Fock (MCDF) method. The tendencies of the shake-up probabilities for both the initially excited and the nonexcited configurations were found to be predicted well in the photoionization by the model used. Based on the calculations, the second shake-up during Auger decay was found to receive considerable high intensity.
