Schmidtke B, Khalil T, Drescher M, Müller N, Kabachnik NM, Heinzmann U. Testing the feasibility of a complete Auger decay experiment by spin- and angle-resolved electron spectroscopy on (XeN4O2,3O2,3P1)-P-3. JOURNAL OF PHYSICS B-ATOMIC MOLECULAR AND OPTICAL PHYSICS. 2000;33(22):5225-5242.The intrinsic parameters beta (1) and gamma (1) were determined separately for the first time by explicit measurement of the angular distribution of the transferred spin polarization of Xe N4O2,3O2,3 P-3(1) Auger electrons after primary excitation with circularly polarized light from the BESSY-II helical undulator UE56/1. The feasibility of a complete experiment for the Anger decay, i.e. extraction of Coulomb matrix elements from the experimental data, is discussed and reveals a new fundamental equation connecting the intrinsic parameters of Anger decay. An analysis procedure is performed, yielding a well confined solution space for amplitude ratios and phase shift differences
