Abstract
A caesium ion beam has been used to excite electron emission from Mg, Al, AlAs and GaAs. The portions of the electron emission spectra that result from Auger transitions are compared with previously reported spectra generated with different primary ion beams. It is observed that 10 keV Cs+-ion bombardment produces very few excited ions with two 2p vacancies. Evidence for two atomic-like peaks discussed by previous authors, but not unambiguously identified, is also presented.
