Abstract The branching ratios of $$p\bar p$$ annihilations into the neutral final states 2π0, π0γ, and 2γ are measured by stopping antiprotons in liquid hydrogen. They are $$B_{2\pi ^0 } = \left( {2.06 \pm 0.14} \right) \times 10^{ - 4} $$ , $$B_{\pi ^0 \gamma } = \left( {1.74 \pm 0.22} \right) \times 10^{ - 5} $$ , andB γγ〈1.7×10−6 (95% c.l.).
