英文摘要	A partial-wave analysis of the reaction pi(-)p-->pi(+)pi(-)pi(-)p at 18 GeV/c has been performed on a data sample of 250 000 events obtained in the Brookhaven experiment E852. The well-known a(1)(1260), a(2)(1320) and pi(2)(1670) resonant states are observed. The existence of the pi(1800), a(1)(1700) and a(4)(2040) states is confirmed. The a(3)(1874) state is also observed. The exotic 1(-+) pi(1)(1600) state produced in the natural parity exchange process is found to decay in the rho(770)pi(-) channel. A mass-dependent fit results in a resonance mass of 1593+/-8(-47)(+29) MeV/c(2) and a width of 168+/-20(-12)(+150) MeV/c(2).
