摘要:
The data presented correspond to theLMMandLMNAuger transitions of silver (some of theLMNtransitions involve valence electrons). Differences in screening are clearly seen by the large change in Auger parameter on going fromLMMtoLMN[see R. Landers, P. A. P. Nascente, S. G. C. de Castro, and G. G. Kleiman, J. Phys. Condens. Matter4, 5881 (1992); Surf. Sci.287, 802 (1993)]. Analysis of theLMMdata tends to indicate the absence of Coster–Kroning decay from theL2toL3initial states, butL1–L2,3cannot be ruled out [see G. G. Kleiman, R. Landers, and S. G. C. de Castro, J. Electron. Spectrosc. (to be published)]. The relatively poor resolution (2.5 eV FWHM for Au 4f) does not seem to have degraded the spectra appreciably since spectra of the more intenseL3M4,5M4,5line taken with higher resolution (1.5 eV FWHM Au 4f) did not show any additional features. The absolute energy accuracy is probably around ± 1 eV but is difficult to quantify for lack of accurate literature data.
