An inclusive γ ray spectrum in p̄p annihilation at rest has been measured with modularized NaI(Tℓ) detectors with statistics several times higher than before. The aim of the experiment was to search for baryonium B in p̄p → γB by detection of narrow lines in the γ ray spectrum. We have not observed any narrow state B with yield greater than 1.5 × 10-3 per annihilation and with statistical significance higher than 2σ.
