Taking the process antiproton proton to omega pi0,omega to pi0 gamma as example the rho matrix of the final state is derived in the helicity formalism taking into account P- and C-conservation.The differential cross section and the gamma polarization observables are calculated using Mathematica.A comparison with similar calculations for the decay omega to pi+ pi+ pi0 is performed.
