TRUE AUGER-ELECTRON SPECTRA MEASURED WITH A NOVEL CYLINDRICAL MIRROR ANALYZER (AU, AG AND CU)

A novel cylindrical mirror analyser (CMA) has been used to obtain true spectra using Auger electron spectroscopy (AES) on Au, Ag and Cu. The whole energy distribution for the primary accelerating voltages, rang ing from 1 V through to 5000 V, was measured absolutely, Even faint sp ectra which have not been cited in Auger data books and only predicted by simple calculation were presented. Auger ionization cross-sections of the M(4) and M(5) shells of Ag and the L(3), M(1) and M(2,3) shell s of Cu were deduced. The energy dependence of the elastically backsca ttered primary electrons was found to show strong material-dependent c haracteristics.
