A study of ..pi../sup -/d interactions at 13.2 GeV/c has been performed using the SLAC 2-m streamer chamber with a forward proton trigger/spectrometer. In this paper, we discuss baryon-antibaryon final states where a forward produced pp-bar enhancement is seen near 2.1 GeV in both pp-barn and pp-bar..pi../sup -/n final states. The measured cross section for ..pi../sup -/d ..-->.. (n/sub s/)pp-barn is 7.6 +- 1.3 ..mu..b and for ..pi../sup -/d ..-->.. ( p/sub s/)pp-bar..pi../sup -/n is 6.6 +- 1.1 ..mu..b in this experiment.
