“…FCSCI is one model to describe, for example, interchannel coupling. Interchannel coupling has significant effects on the angular distribution of photoelectrons, for example, in the region of the xenon 4d shape resonance [56] or above threshold [57].…”

This review covers the outer core level photoionization of the free 3d metal atoms from Sc to Cu. The experimental 3p, 3s and 2p photoemission and photoabsorption spectra are discussed. A comparison emphasizes common features and distinct differences. The interpretation of the data based on ab initio calculations reveals the influence of multi-electron interactions in the 3d metal atoms. We focus on the fundamental effects and main interactions which govern the electronic structure of these open shell atoms.

“…(1997). On the other hand, only very recently, photoionization of heavy atoms with partly filled and polarized subshells led to analyses of 'complete experiments' even with spin or orientation, correlations from outer to inner electron subshells of the atoms (Prümper et al . 1999;von dem Borne et al .…”

In this paper, we initially list 23 subfields of the research topics associated with the title of this paper. Then we present a detailed theoretical description of polarizedelectron interactions with atoms and molecules. Spin effects based on Coulombdirect, Coulomb-exchange and spin-orbit interactions in light and heavy atoms are described, and experimental data are presented as tests for relevant theoretical approximations.Electron-scattering interactions with orientated molecules such as CH 3 I and CH 3 Cl show interesting alignment and orientation effects, which are new types of test quantities for the theory of such electron-scattering processes with molecules.Numerous multielectron effects determine photoionization of atoms in general. Spin, and spin-orbit interaction effects particularly, can be studied by photoelectron spin experiments and by applying polarized atoms in the photoionization process. The former type of experiment has been used very successfully in the photoionization of rare gas atoms, while the latter type of experiment and related theories have been applied particularly for photoionization with partly filled subshells. Out of such photoionization experiments with polarized atoms we selected one involving oxygen atoms {O(1s 2 2s 2 2p 4 ) 3 P 2 + hν} for a more detailed description.While the photoionization process with unpolarized oxygen atoms is characterized by the cross-section, σ, and the angular distribution parameter, β, only; a further parameter, β , is required for photoionization with polarized oxygen atoms. Alternatively, it is possible to describe the photoionization of polarized oxygen atoms by deriving β and β from the ratio of two reduced matrix elements for s and d electrons and their relative phase difference. Keywords: polarized-electron and polarized-atom interactions; scattering of electrons by orientated molecules; photoionization of polarized atoms; 'complete' scattering experiments

“…There are several ways to probe the photoionization dynamics of free atoms. The characterization of the photoelectrons, Auger electrons and photons emitted upon ionization according to their energy, angular distribution and spin polarization as well as coincidence techniques or the photoionization of polarized atoms with polarized photons have been applied successfully [1][2][3][4][5][6]. The latter technique, namely the determination of dichroism in the photoelectron spectra for different atomic polarizations and fixed polarization of the ionizing radiation, in a recent investigation of the Eu 4f photoionization [7] has been proven to be a very sensitive probe for electron correlation.…”

The 4f and 5p subvalence photoionization of atomic Tm has been investigated by combining high-resolution photoelectron spectroscopy and dichroism measurements of the laser-polarized atoms. The experimental results are compared to Hartree–Fock calculations. The Tm 5p photoelectron spectrum is dominated by spin–orbit splitting whereas mixing of the final ionic states strongly influences the Tm 4f photoionization. Intermediate coupling is appropriate for the explanation of the complex Tm 4f multiplet structure, though some lines are well described within LS coupling. This suggests a partial breakdown of the LS-coupling approximation for Tm 4f photoionization. In comparison to the corresponding spectra of Eu the Tm spectra are much less affected by the admixture of 6s5d and 5d2 valence electron configurations.
