XPS BINDING-ENERGIES OF DEEP CORE LEVELS AND THE AUGER PARAMETER - ANAPPLICATION TO SOLID SULFUR-COMPOUNDS

X-ray photoelectron spectroscopy/X-ray excited Auger electron spectros copy investigations of solid sulfur compounds are reported. Deep S 1s core level binding energies were measured in addition to the common S 2p level and the KLL Auger spectra to derive the Auger parameters. Loc al and solid state effects on the binding energies were identified usi ng both core levels within an initial state-final state framework. The results are discussed in comparison to recent data on phosphorus comp ounds. The information from the deep core level is emphasized.
