An XPS electron was found to have a kinetic energy of 1052.6 e V when ejected with an AI Ka source (λ = 0.83393 nm) and measured in a spectrometer with a work function of 27.8 e V The electron is believed to be a N(1s) electron in NaNO3·
(a) What was the binding energy for the electron?
(b) What would be the kinetic energy of the electron if a Mg Ka (λ = 0.98900 nm) source were used?
(c) How could one be sure that a peak was an XPS and not an Auger electron peak?
(d) At what binding and kinetic energies would a peak for NaNO2 be expected when the Al Ka source was used with the same spectrometer?
