We have measured the differential cross section for π-p→η0n at 6.0 GeV/c from 6730 very clean events in which the decay η→π+π-π0 was detected. The high statistics reveals a sizable forward turnover, implying a dominance of the helicity-flip amplitude. A precisely determined A2 trajectory, linear for |t|<1.0 (GeV/c)2, is found from combining our data with those at energies up to 101 GeV.
