The kinetic energies of the photoelectrons that are ejected from the atoms are measured. In photoelectron spectroscopy a beam of x-rays is directed at a sample of atoms. The x-rays have much more energy than is necessary to knock these electrons out of the atom, producing a stream of electrons called “photoelectrons”. Photoelectron Spectroscopy - Mr WEld's Homepage. Photoelectron Spectroscopy 1 Photoelectron Spectroscopy 4 ™ Activities for AP* Chemistry POGIL 13. If the kinetic energy of the photon is exactly equal to the ionization energy, the kinetic energy of Justify your answer. Model 4 – Photoelectron Spectra of Lithium 21.

Thus all the peaks would have a larger ionization energy as compared with Ar. 2) The photoelectron spectrum of 16 O and 18 O should be the same. True. Neutrons have no effect on Coulombic forces, so the spectra should be the same.
