Abstract

The influence of He+ ion impact on the Ar LMM spectra was investigated at the ESA-21 electron spectrometer using three different ion energies. Observed line relative energies to the L3M2,3(1D2) line agree well with other results, but the relative intensities of five angular-isotropic lines deviate significantly from other measurements and theory. The angular dependence of energy shifts agrees with the quantum PCI theory of Barrachina and Macek, except for directions close to 180°, where a slight enhancement of energy shift was observed. Finally, the angular distributions of the L2M2,3(1S0), (1d2) and (3P0,1,2) line intensities were compared to the alignment theory of Sizov and Kabachnik.
