Abstract
We have studied the angular distributions for the reaction for the mass range 1350-1530 MeV. These data are used to study the amplitudes below threshold. The analysis confirms previous SU(3) multiplet assignments for the and , and indicates that the channel is dominated by a repulsive background with the being a small effect superimposed on the background. This conclusion is at odds with the usual -matrix analysis of the low-energy data but is somewhat supported by recent evidence from baryon-exchange production of the .
