The results of an amplitude analysis to determine the spin-parity components of the $K\sp+{\bar K\sp0} \pi\sp{-}$ system produced in the reaction ${\bar p}p\to K\sp+{\bar K\sp0}\pi\sp-$ + X at 8 GeV/c are presented. This experiment has better particle identification than the previously reported results examining this reaction. A total of 3595 events was collected in the mass range 1.24-1.56 GeV/c$\sp2$. The data were collected at the Brookhaven National Laboratory Multi-Particle Spectrometer. Two peaks are observed in the $K\sp+{\bar K\sp0}\pi\sp-$ mass spectrum, one at (1279 $\pm$ 2) MeV/c$\sp2$ with a width of 21 $\pm$ 2) MeV/c$\sp2$, and one at (1417 $\pm$ 3) MeV/c$\sp2$ with a width of (62 $\pm$ 5) MeV/c$\sp2$. / There is evidence for two resonances around 1.3 GeV/c$\sp2$. The $J\sp{PG}$ = 1$\sp{++}$ resonance that peaks near 1.27 Gev/c$\sp2$ is identified with the $f\sb1$(1285). The $J\sp{PG}$ = 0$\sp{-+}$ resonance observed at the same mass is identified with the $\eta$(1280). / In the 1.4 GeV/c$\sp2$ range, the data are consistant with the presence of at least one $J\sp{PG}$ = 0$\sp{-+}$ resonance that peaks near 1.43 GeV/c$\sp2$. This resonance decays only to $a\sb{0}\pi$. There is also evidence for a 1$\sp{++}K\sp{\*}K$ resonance that peaks around 1.40 GeV/c$\sp2$. These results are in agreement with the results from the partial wave analysis performed by members of this collaboration on the $K\sp+{\bar K\sp0}\pi\sp-$ system produced in the reaction $\pi\sp-p\to K\sp+{\bar K\sp0}\pi\sp-n$ at 8 GeV/c. / This experiment also examined the reactions ${\bar p}p\to{\bar \Lambda}p+\pi s+X$ in a search for the U(3100). No evidence for the U(3100) is observed. / Source: Dissertation Abstracts International, Volume: 51-09, Section: B, page: 4405. / Major Professor: Vasken Hagopian. / Thesis (Ph.D.)--The Florida State University, 1990.
