Partial wave analysis of

A partial wave analysis of PS185 data for is presented. A 3 S 1 cusp is identified in the inverse process at threshold, using detailed balance to deduce cross sections from . Partial wave amplitudes for 3 P 0, 3 F 3, 3 D 3 and 3 G 3 exhibit a behaviour very similar to resonances observed in Crystal Barrel data. With this identification, the data then provide evidence for a new I = 0, J PC = 1- resonance with mass MeV, MeV, coupling to both 3 S 1 and 3 D 1.
