The annihilation channel p̄p → K+K-π0 in liquid hydrogen at rest has been studied with the Crystal Barrel detector at LEAR. The measured branching ratio is: BR(p̄p → K+K-π0) = (2.37 ± 0.15) × 10-3. A partial wave analysis shows that this reaction is dominated by the π(KK̄)S, KK *(892) and πφ(1020) intermediate states. Weak signals are observed for πa2(1320), πf2(1270), πf′2(1525) and K(Kπ)S. A satisfactory description of the Dalitz plot requires the introduction of π(KK̄)P intermediate states with at least one pole.
