Backward resonance production in pi minus plus proton goes to neutron pi plus pi minus at 8 GeV/c
… triggered on the interaction of a fast, forward neutral hadron in thick plate optical spark chambers. A total of 866 events had an acceptable 3-constraint fit to n p ~ nn nand satisfied other selection criteria. The data was characterized by backward production of the final states npo, nfo, and …

Observation of quasi two-body production in pion plus proton goes to neutron plus four charged pions at 8 geV/c
… 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 …

Backward production in pi minus plus proton goes to neutron pi plus pi minus at 8 GeV/c
… was triggered by the detection of a fast forward neutral hadron interacting in an array of thick plate optical spark chambers. The dominant feature of the data is quasi two body production of npo and nfo intermediate states. The differential cross section for po production shows evidence for …
