Abstract
The annihilation channels $\bar{p}p$ $\rightarrow$$\omega$$\pi^0$, $\omega$$\eta$, $\omega$ $\eta^{\prime}$were studied with the CRYSTAL BARREL DETECTOR AT LEAR AT -MOMENTA OF 600, 1200, AND 1940 MEVC. IN MOST CASES ANGULAR DISTRIBUTIONS WERE MEASURED WHICH ALLOWED A COMPLETE JP-ANALYSIS USING THE HELICITY FORMALISM. THE CONTRIBUTION OF ALL RELEVANT INITIAL STATES COULD BE DETERMINED. THE MAXIMAL CONTRIBUTING ANGULAR MOMENTA ARE DEPENDENT ON THE -MOMENTUM AND RANGE UP TO J=5.
