| Abstract | Cross sections of the reaction K/sup -/p to pi /sup +/ pi /sup -/ pi /sup 0/ Lambda are determined in a bubble chamber study at 10 incoming beam momenta between 1.425 GeV/c and 1.800 GeV/c. For the subsample K /sup -/p to omega Lambda , cross sections and angular distributions are presented together with their legendre polynomial expansions and those of the single and joint density matrix elements. An energy dependent partial-wave analysis is performed including earlier data. The data is well fitted by constant background amplitudes in the outgoing S, P and D waves plus two I=0 resonances in this region, the well established G/sub 7/ Lambda (2100) and the P/sub 3/ Lambda (1870) .
