Comment on ‘‘Photoemission study of the existence of a valence-band satellite in Fe’’

Abstract
Recently, Kato et al. [Phys. Rev. B 32, 1992 (1985)] reported photoemission spectra on iron and suggested that the peak that we attributed to a valence-band satellite in a previous work [Phys. Rev. B 27, 2630 (1983)] could be due to oxygen contamination of the surface or to emission from the sp band. We present here polarization-dependent spectra which enable us to separate the sp-band emission and the valence-band satellite and show that our spectra are very similar to ones obtained by Kato et al. on the clean surface.
