摘要：

We have carried out a study of the reaction pi-p --> f1 (1285)pi-p at 18 GeV/c, with f1 (1285) --> K+K0pi-BAR This reaction is almost entirely mediated by the natural-parity exchange, presumably f2 (1270) or rho exchange. We find evidence for two possible resonances - a J(PC) = 1++ state at 1.7 GeV/c2 and a broad J(PC) = 1-+ structure at 1.6-2.2 GeV/c2.
