In XPS the photon is absorbed by an atom in a molecule or solid, leading to ionization and the emission of a core (inner shell) electron. By contrast, in UPS the photon interacts with valence levels of the molecule or solid, leading to ionisation by removal of one of these valence ...
It was found that the half-width of the O Kα band decreases somewhat but that of the XP valence-band spectrum increases when going from h-WO3 to CuWO4, however the energy positions of the maxima and of the centres of gravity of the O Kα band remain constant for the above compounds...
He I, He II and Al Kα photoemission spectra of the valence band of α-MnS are reported. The He I and II spectra were obtained on a crystal platelet (bounded by (111) planes), the Al Kα spectrum was from a polycrystalline sample. The strong dependence on hν of the photoionization...
