Abstract
On the basis of improved multiconfiguration Hartree-Fock calculations for the ground states of Ca, Sr, Ba, Zn, Cd, and Hg it is confirmed that recent photoelectron satellite spectra obtained by Süzer, Lee, and Shirley do require for the interpretation of the observed satellite intensities knowledge of more than just the ground-state composition. The relevant dipole matrix elements between initial and final states are also needed. It is noticed that photoelectron spectroscopy allows the observation of the relaxation of atomic orbitals on a time scale determined by the kinetic energy of the photoelectron.Keywords
