The effect of relaxation on KLL, LMM, and MNN Auger-electron spectra of Ne, Mg, Ar, Ca, Zn, and Kr has been studied by the Dirac-Fock method. The relaxation is shown to depend universally on the Auger-electron energy aud on the number of peel electrons (N") in subshells above the final-state holes. In the sudden approx-imation limit (large N") the relaxation saturates to 14%%uo reduction of the Auger rates in analogy to the 20'Fo reduction of deep inner-shell Dirac-Fock photoionization cross sections well above threshold. The isotropy of the relaxation is emphasized by its small influence on the angular distribution of Auger electrons. PACS number(s): 32.80.Hd, 32.80.Fb

The satellite structure due to the configuration interaction (CI) and shakeup process from 6s to 7s has been studied in the 4d, 5s and 5p photoelectron spectra of Cs and Ba. Spectra have been compared with each other and with the results of multiconfiguration Dirac-Fock calculations. Theoretically determined total intensities of CI satellites, shakeup probabilities and energies have been found to be in good general agreement with experiment.
