Spin-resolved electron spectroscopy of the xenon N4,5O2,3O2,3 Auger lines

The spin polarization of the Xe N4,5O2,3O2,3 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 transmiss ion multilayer acting as a quarter-wave plate. Nearly perfect circular pola rization was obtained. In the framework of the two-step model of Auger deca y the orientation of the primary hole stales 4d(-1) D-2(3/2) and 4d(-1) D-2 (s/2) can be derived from the spin polarization of the S-1(0) Auger lines. Furthermore, the intrinsic parameters for all lines in this Auger group cor responding to the other 5p(-2) final states are determined and compared wit h theory.
