Electron energy-loss spectroscopy of autoionizing states of zinc

Abstract

Autoionizing energy-loss spectra of Zn from 10.8 to 12.5 eV, for incident electron energies between 20 and 100 eV, have been recorded at scattering angles from 0° to 10°. These spectra were decomposed using χ2 minimization procedure to show the contribution of the 3d 10 4s 2 → 3d 9 4s 2 4p, single inner-electron transitions. Relative intensities of lines in the Zn spectra are determined with respect to the 3d 10 4s 2 → 3d 10 4s4p resonance line. The line shapes and widths are examined. The results are compared with available measurements and theoretical estimates.
