Surface Composition

Question 1

relaxation of core-hole stated caused by excitation

Answer 1

x-ray fluorescence where electron relaxes down
auger emission where one electron goes down and another goes up

Question 2

analysis of Auger emission spectra

Answer 2

large peak due to secondary electrons produced by inelastic scattering, characteristic peaks due to binding energy and environmental effects, plasmon quantised loss peaks and elastic peak with electron excitation only
