An alternative method to the density matrix formalism for the derivation ofgeneral expressions of the interaction of polarized atoms with polarizedphotons and electrons is presented. The expression for the cross-sectiondescribing the polarization states of all particles taking part in the processare obtained in the form of an expansion via irreducible tensors that have themost simplest possible behaviour under changes of directions. The ways of theapplication of the general expressions suitable for the specific experimentalconditions are outlined by deriving asymmetry parameters of the angulardistributions of photoelectrons and Auger electrons following photoionizationas well as the parameters of the angular correlations between photo- and Augerelectrons.Comment: 19 page
