Description
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 a1(1260), a2(1320) and pi2(1670) resonant states are observed. The existence of the pi(1800), a1(1700) and a4(2040) states is confirmed. The a3(1874) state is also observed. The exotic 1-+ pi1(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/c2 and a width of 168±20-12+150 MeV/c2
