Study of the $K^{+}K^{-} \pi^{+}\pi^{-}\pi^{0}$ final state in antiproton annihilation at rest in gaseous hydrogen at NTP with the OBELIX spectrometer

A spin-parity analysis of a sample of pp to K/sup +/K/sup -/ pi /sup +/ pi /sup -/ pi /sup 0/ annihilation events taken at rest in gaseous H/sub 2/ at NTP is reported. The invariant mass spectrum of the K/sup +/K/sup -/ pi /sup 0/ system shows the presence of the E/t resonance pattern at 1.42 GeV. T...
