In this article, the pole strengths of the Green's functions were used to explain the relative intensities of satellite lines in the photoelectron spectra, which arise due to excitations accompanying photoionization.Abstract:
The method of Green's one-particle functions is used to explain excitations with simultaneous ionization in atoms and molecules. The relative intensities of satellite lines in the photoelectron spectra, which arise due to excitations accompanying photoionization, are found to be simply related to the pole strengths of the Green's functions. For the water molecule many such satellite lines are calculated to be in the region of 25–80 eV binding energy.read more

One-body Green's function for atoms and molecules: theory and application
TL;DR: In this paper, the authors investigated the contribution of higher orders of the self-energy part up to third order and found that the main contributions due to this interaction can be determined by considering the analytic properties of second and third order terms only.
