Abstract
An analysis of the reaction at 2.0- incident momentum is presented. The total cross section for the reaction is 627±20 , based on 4519 events. The reaction is dominated by resonance production through several channels which overlap kinematically but do not appear to interferesubstantially. A maximum-likelihood procedure was used to determine the production fractions, which for the major channels are 0.44±0.02 for , 0.145±0.02 for , 0.10±0.03 for , and 0.20±0.02 for simultaneous . Evidence is presented for the production of and its decay into as well as for production of with decay into . A four-standard-deviation enhancement is present at a invariant mass of 690 MeV. Angular correlation data are presented for the , , and reaction channels. However, the difficulty of separating the various channels prevents a detailed study of the reaction dynamics.
