Eisenstein, Bob I. Wroblicka, William Thaddeus 2011-06-27T15:31:17Z 2011-06-27T15:31:17Z 10000-01-01 1980 This thesis reports the first observation of quasi 2-body production in the backward reaction pi- P -> npi+pi+pi-pi-. Data were obtained using an 8 GeV/a pion beam incident on a liquid hydrogen target inside the University of Illinois/Argonne National Laboratory streamer chamber. The chamber was triggered by the interaction of a fast, forward neutral hadron in thick plate optical spark chambers. Total backward cross sections are derived for the processes pi-P -> N*o (1520)+p°/f°, N*o (1670)+po/fo I delta° (1890)+p°/f° I and delta-(1236)+A2+. Evidence for a narrow Ai resonance is not seen. Corrections for losses due to finite acceptance are made using Monte Carlo techniques based on a simple baryon exchange model. Comparison is made to another experiment regarding the energy dependence of certain cross sections and a simple power law behavior is observed.
