Satellite structure in the x-ray photoelectron spectra of Fe(III) halides: Evidence of multielectron excitation and multiplet structure

The satellite structure in the x-ray photoelectron spectra of Fe(III) halides and of MnCl₂ has been measured, particular attention being paid to the $2p$, $3s$ metal subshells and the valence region. The nature of the phenomena giving rise to these satellites and their relative importance in each spectral region, is discussed with reference to known theoretical results.
