Production cross sections and angular distributions of LAMBDA and K/ sup 0/ particles produced by 11.4 Bev/c pi /sup -/ mesons in hydrogen were measured. A systematic investigation was made of all two-body decays of unstable neutral particles. No events inconsistent with gamma , LAMBDA , or K/sup 0/ were found. Production cross sections, angular distributions, and effectlve mass distributions of pi mesons produced in 4-prong events were also measured. No evidence for dominance of any high-mass multi-pion resonance was found. Both the pion production and strange-particle production reactions demonstrated peripheral characteristics in that the baryon was strongly peaked backward in the center of mass. The average transverse momentum was observed to be a monotonically increasing function of mass. The experimental total interaction cross-section was (25.3 plus or minus 1.5) mb. The effect of the pion-nucleon T = 3/2 isobar was clearly observed. (auth)
