Interactions of 224-Mev negative pions with protons were investigated using a 15-cm hydrogen bubble chamber in a 13-kgauss field. Seventeen hundred elastic scatterings were analyzed yielding a cross section of 16.0 plus or minus 0.8 mb for this process. No evidence for powers of cos theta higher than two was observed in the angular distribution. The chargeexchange cross section, based on 1200 events was 34.4 plus or minus 1.9 mb. The results of a random- search phase-shift analysis, using these data in conjunction with earlier pi -p elastic scattering results and recoil proton polarization measurements ( pi --p), are reported. A search for pion production yielded three events of the type pi + p yields pi - + pi + n corresponding to a cross section of approximates 30 mu b. No events of the type pi - + p yields pi /sup -/ + pi /sup 0/ + p were observed. (auth)
