Abstract

A partial-wave analysis of the reaction (Formula presented) at (Formula presented) has been performed on a data sample of 250 000 events obtained in the Brookhaven experiment E852. The well-known (Formula presented) (Formula presented) and (Formula presented) resonant states are observed. The existence of the (Formula presented) (Formula presented) and (Formula presented) states is confirmed. The (Formula presented) state is also observed. The exotic (Formula presented) (Formula presented) state produced in the natural parity exchange process is found to decay in the (Formula presented) channel. A mass-dependent fit results in a resonance mass of (Formula presented) and a width of (Formula presented).
