SPIN-POLARIZED AUGER ELECTRONS - THE XE M(4,5)N(4,5)N(4,5) CASE

The spin polarization of the Xe M(4,5)N(4,5)N(4,5) Auger electrons was measured after photoionization of free atoms by circularly polarized synchrotron radiation at 834.5 eV. Significant polarization effects we re found across the whole Auger group. With the hole state orientation determined from the spin polarization of the M(4)(1)S(0) Auger line t he intrinsic Auger parameters were evaluated for all lines. orientatio n derived from the S-1(0) Auger line is consistent with the measured s pin polarization of the 3d(3/2) photoline in good agreement with the t wo-step model of the Auger decay.
