- Abstract
The Th 5p photoelectron spectrum of the ThO2 oxide exhibits an anomalous spin–orbit splitting, intense satellite, and a poorly observable very strongly broadened Th 5s line. The Th 5p and Th 5s photoelectron spectra are calculated in this work using the configuration interaction and spectral (Green's) function methods in the basis of atomic Hartree–Fock functions. The results are in good agreement with experiment and indicate that the structure of these spectra is determined by interactions of the photoionization-induced 5p–1 and 5s–1 states with the 5d–25 f (ε f) and 5p–15d–1(ε f) satellite states including two holes and one electron in the discrete or continuous spectrum.
