An experiment designed to study baryon exchange reactions in ..pi../sup -/p scattering at 4 GeV/c is discussed. The experiment was performed at the Bevatron and utilized a streamer chamber and a downstream spectrometer which consisted of two scintillation counter hodoscopes and a Cerenkov counter to define the fast proton trigger, and two planes of spark chambers to provide improved resolution on the forward track. Analysis of meson production in the reactions ..pi../sup -/p ..-->.. pM/sup -/, ..pi../sup -/p ..-->.. p..pi../sup -/M/sup 0/, ..pi../sup -/p ..-->.. Lambda/sup 0/M/sup 0/ is discussed for backward production of meson systems M/sup -/ and M/sup 0/. Differential cross sections and decay distributions (where applicable) for ..pi../sup -/, rho/sup -/, rho/sup 0/, f/sup 0/, omega/sup 0/, eta/sup 0/, and K*/sup 0/ production are discussed. Upper limits for A/sup -//sub 1/, A/sup -//sub 2/, and B/sup -/ production are given. Baryon resonance production and limits on exotic meson production are briefly discussed.
