摘要：

We have determined ratios of branching ratios for ppBAR annihilations at rest into pi0eta and pi0eta', into etaeta and etaeta', and into omegaeta and omegaeta'. All reactions are observed in two different all-neutral final states. The ratios permit a determination of the pseudoscalar mixing angle. We find THETA(PS) = -(17.3 +/- 1.8)-degrees.
