Abstract
The density matrix parametrization of collisionally excited atomic ens embles is generalized to account for a projectile spin. The elements a re related to the ''generalized Stokes parameters'' of Andersen and Ba rtschat [J. Phys. B 27, 3189 (1994)], determined in scattered-projecti le-polarized-photon coincidence experiments after impact excitation by spin-polarized electrons. The well-established orientation propensity rule for unpolarized electron beam experiments is nor valid for spin- resolved collisions.
