NIST X-ray Photoelectron Spectroscopy Database (SRD 20), Version 5.0
Reliable (reported energy within 300 eV of a reference energy)
Comment:
FeS2(100). The composition determined by XPS was FeS1.9. The sample was cleaned by He+ ion bombardment (Ep = 200 eV, time = ~10 min) and annealed (T = 573 K, time = ~5 min). The intensity ratio of the Gaussian/Lorentzian components was 80/20. Branching ratio = 0.5. FAT mode.
