Differential cross sections and density-matrix elements in rho/sup -/ decay have been measured at 6 GeV/c for p-barp ..-->.. ..pi../sup +/rho/sup -/ and its line-reversed partner ..pi../sup -/p ..-->.. prho/sup -/ in the range t/sub min/ > t > - 1.5 (GeV/c)/sup 2/. The reactions satisfy line-reversal symmetry and the rho/sup -/ decay is consistent with isotropy for -t < or = 0.5(GeV/c)/sup 2/. For -t > or = 0.5(GeV/c)/sup 2/, the differential cross sections show a weaker t dependence, and the decays become anisotropic.
