Differential cross sections have been measured for p-barp ..-->.. ..pi../sup -/..pi../sup +/ (1) and its line-reversed partner ..pi../sup +/p ..-->.. p..pi../sup +/ (2) in the range t/sub min/ > t > - 1.5 (GeV/c)/sup 2/ at 6 GeV/c. Clear structure is seen in the differential cross section for Reaction (1) at t approx. - 0.4 (GeV/c)/sup 2/. However, this feature is quite different from the striking dip seen in (2) at t approx. - 0.15 (GeV/c)/sup 2/, this difference indicating a failure of line reversal and disagreement with simple Regge models.
