Spin-resolved electron spectroscopy of the xenon $\mathrm{N_{4,5}O_{2,3}O_{2,3}}$Auger lines

The spin polarization of the Xe N4,5 O2,3 O2,3 Auger lines was measured after ionization by circularly polarized synchrotron radiation of 93.8 eV photon energy. The circularly polarized radiation was produced by converting the linearly polarized light from a conventional undulator by a Mo/Si transmission multilayer acting as a quarter-wave plate. Nearly perfect circular polarization was obtained. In the framework of the two-step model of Auger decay the orientation of the primary hole states 4d-1 2D3/2 and 4d-1 2D5/2 can be derived from the spin polarization of the 1S0 Auger lines. Furthermore, the intrinsic parameters for all lines in this Auger group corresponding to the other 5p-2 final states are determined and compared with theory
