Abstract
The photoionization of free Cr atoms has been studied. Unpolarized as well as laser-aligned Cr atoms have been ionized with linearly polarized undulator radiation well above the ionization thresholds. The investigation of the main and satellite photoelectron lines and of the linear alignment dichroism allowed for a detailed characterization of the Cr photoionization process. The spectra are compared to the predictions of the pure coupling model and to the results of intermediate coupling Hartree-Fock calculations. The importance of the investigations for the discussion of the photoelectron spectra of bound transition-metal atoms is pointed out.
