In: Correlations, Polarization, and Ionization in Atomic Systems pp 32-37 (Eds.) Madison, D. H. and Schulz, M., AIP, Melville/New York, USA 2002An experiment has been performed in which a polarized electron beam ionizes an orbitally oriented and/or spin polarized valence electron of sodium. The cross section for this reaction is measured for well-resolved vector momenta of the two electrons in the final channel. An tensorial re-coupling scheme has been developed in which the measured quantities are expressed in terms of independent, irreducible spherical tensor components. For a comparison with experiment we performed numerical ionization-cross section calculations within the Distorted Wave Born Approximation (DWBA) and the Dynamically Screened Three coulomb Waves (DS3W) theory.
