Two and four prong (pi)('+)p interactions at 16 GeV/c were used to study the reactions: (pi)('+)p (--->) p(pi)('+)(pi)('+)(pi)('-)(eta), (pi)('+)p (--->) p(pi)('+)(eta) and (pi)('+)p (--->) p(pi)('+)(omega). The data were taken by the SLAC 1 meter hybrid bubble chamber facility augmented with a lead glass wall assembly for forward going neutral energy detection. The wall was used to trigger the bubble chamber for neutral energy greater than 3 GeV. / The detection of the (eta) and (pi)('0) signals is shown in the neutral missing mass of the 2 and 4 prongs. A strong (DELTA)('++) signal is seen in both 2 and 4 prong topologies. The invariant mass for the (eta)(pi)('+),(eta)(pi)('-),(eta)(pi)('+)(pi)('-),(pi)('+)(pi)('-)(pi)('0) and (omega)(pi)('+) are given but no new high mass resonances were found. / The cross section for (pi)('+)p (--->) (pi)('+)(pi)('+)(pi)('-)p(eta), (eta) (--->) neutrals production was calculated to be 72 (+OR-) 20 (mu)b, while for the (pi)('+)p (--->) (pi)('+)p(eta), (eta) (--->) neutrals it was 31 (+OR-) 8 (mu)b. The cross section for the production of the (pi)('+)p (--->) (pi)('+)p(omega) was 45 (+OR-) 8 (mu)b and (pi)('+)p (--->) (DELTA)('++)(omega) was found to be 16 (+OR-) 2 (mu)b. / Signals were observed and cross sections calculated for the following mesonic resonances: (delta)('(+OR-))(980) (--->) (eta)(pi)('(+OR-)):(sigma) (.) BR = 13 (+OR-) 5 (mu)b, (eta)' (--->) (eta)(pi)('+)(pi)('-):(sigma) (.) BR = 8 (+OR-) 3 (mu)b and B('+)(1235) (--->) (omega)(pi)('+):(sigma) = 11 (+OR-) 2 (mu)b. Cross sections for resonances opposite (DELTA)('++) were found: (eta)'(980):(sigma) = 6 (+OR-) 1.8 (mu)b and D('0)(1285):(sigma) = 4 (+OR-) 1 (mu)b. / Source: Dissertation Abstracts International, Volume: 45-01, Section: B, page: 0235. / Thesis (Ph.D.)--The Florida State University, 1984.
