From a bubble chamber exposure in an antiproton beam at 5.7 GeV/ c yielding 13 events/μb, the final states p ̄ p → Y 1 ∗+ (1385)Λ, Y 1 ∗+ (1385)Σ + , Y 1 ∗+ (1385) Y 1 ∗+ (1385) have been isolated. We have measured the total cross section, d σ /d t , and the complete density matrix of the Y ∗ for these processes. Upper limits have been set to the forbidden reactions p ̄ p → Y 1 ∗− (1385)Σ − , Y 1 ∗− (1385) Y 1 ∗− (1385) .

STUDY OF THE REACTION ANTI-P N ---> ANTI-P P PI- AT 2.98-GEV/C

The reaction p n → p p π − at 2.98 GeV/ c is studied with high statistics. The dominant Δ −− production is found in the framework of the additive quark model to proceed mainly through unnatural parity exchange in the t -channel. A detailed comparison with the reaction K − p → K ∗0 n confirms, for the dominant part of the cross section, the predictions of the quark model.
