We have performed an experiment in the Antiproton Accumulator at Fermilab to study two-body neutral final states formed in [Formula presented] annihilations. Differential cross sections are determined in the center-of-mass energy range [Formula presented] GeV for the final states [Formula presented] [Formula presented] ηη, [Formula presented] and γγ. The energy dependence of differential cross sections at 90° in the center of mass is studied to test the predictions of phenomenological QCD scaling hypotheses which predict power-law dependence.
