Abstract

The branching ratios (Br) for the Pontecorvo reactions p̄ d →- nπ0, nη, nω, nη', and Δ0(1232)π0 are presented. The data were obtained at LEAR by stopping antiprotons in a liquid deuterium target. Outgoing mesons have been fully reconstructed. Assuming charge independence, Br(p̄ d → nπ0) was compared with measurements of the reaction p̄ d → pπ-. No substantial difference between Br's for the Pontecorvo reaction p̄ d → pπ- in liquid and gaseous deuterium has been observed. The π0π0n Dalitz plot was used to identify the reaction p̄ d → Δ0π0.
