Multiple Photoelectron Processes and their Relationship to Electron Energy Spectra

Some processes are discussed in which more than one electron is ejected by an atom which absorbs a photon.

Description
Summary:Some processes are discussed in which more than one electron is ejected by an atom which absorbs a photon. Illustrations are given from the measured photoionization cross-sections in the production of Xe$^{2+}$, Xe$^{3+}$, Cd$^{2+}$, and Zn$^{2+}$ by monochromatic vacuum ultraviolet radiation of energy less than 85 eV. Of photons absorbed at 63 eV, 30% produce doubly charged ions in Xe and Cd, and 20% do so in Zn, all by direct emission. The role which double electron emission and single and multiple Auger electron emission may play in electron energy measurements is brought out, and the relationship with atomic theory is briefly discussed.
