We present analytical and numerical results for the alignment polarization and its polar angle dependence. We discuss in some detail the zero-mass limit of our results and the role of the anomalous spin-flip contributions to the polarization observables in the zero-mass limit. Our discussion includes transverse and longitudinal beam polarization effects.33 pages, LaTeX, 4 figures are included in PostScript formatHigh Energy Physics - Phenomenologytext
