We have performed an experiment in the Antiproton Accumulator at Fermilab to study two-body neutral final states formed in <(pp)over bar> annihilations. Differential cross sections are determined in the center-of-mass energy range 2.911< root s<3.686 GeV for the final stares pi(0) pi(0), eta pi(0), eta eta, pi(0) gamma, and gamma gamma. The energy dependence of differential cross sections at 90 degrees in the center of mass is studied to test the predictions of phenomenological QCD scaling hypotheses which predict power-law dependence.
