Sarma, DD and Speier, W and van Acker, JF (1991) Comment on "X-ray-photoelectron diffraction from a free-electron-metal valence band: evidence for hole-state localization". In: Physical Review Letters, 66 (21). pp. 2834-2835.Full text not available from this repository. (Request a copy)
In a recent Letter,' Osterwalder et al. (hereafter referred to as OGHS) presented some interesting data of x-ray-photoelectron diffraction (XPD) from Al. The XPD results from the core level and from the valence region are found to be strikingly similar; this prompted the authors to suggest that the hole state in the valence band following photoionization may be similarly localized as in the core level. Here we wish to point out that there is an alternate explanation for their experimental observations, without invoking hole-state localization in the valence-band photoionization.
