A partial-wave analysis of the reaction π−p→π+π−π−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 a1(1260), a2(1320) and π2(1670) resonant states are observed. The existence of the π(1800), a1(1700) and a4(2040) states is confirmed. The a3(1874) state is also observed. The exotic 1−+ π1(1600) state produced in the natural parity exchange process is found to decay in the ρ(770)π− channel. A mass-dependent fit results in a resonance mass of 1593±8−47+29 MeV/c2 and a width of 168±20−12+150 MeV/c2.
