Abstract

The annihilation channels $\bar{\rm p}{\rm p}\to \omega\pi^0, \omega\eta, \omega\eta^\prime$ were studied with the Crystal Barrel detector at LEAR at $\bar{\rm p}$ -momenta of 600, 1200, and 1940 MeV/ $c$ . In most cases angular distributions were measured which allowed a complete $J^P$ -analysis using the helicity formalism. The contribution of all relevant initial states could be determined. The maximal contributing angular momenta are dependent on the $\bar{\rm p}$ -momentum and range up to J = 5.
