We propose to study 300 GeV/c $$π^{-}p$$ interactions at NAL with a hybrid bubble chamber-optical spark chamber spectrometer system. The inclusive reaction $$π^{-}p$$→$$π^{-}+$$ anything will be studied in detail. We will measure distributions of the scaling variable x, the transverse momentum a, and the charge-multiplicity n and their interdependence over a wider range of x than is otherwise obtainable. These and related distributions will be compared with the predictions of current models for high energy interactions. The experiment will extend Notre Dame measurements at conventional accelerator energies (8 and 18.5 GeV/c) to energies where asymptotic approximations may be valid and discrimination among the models should be possible. In addition we will study those "exclusive" reactions such as target and / or beam diffraction dissociation if cross sections remain significant. We believe that significant results can be obtained within 2-3 months of data acquisition.
