A total of 1121 unambiguously identified events of the type $$\bar pp \to \bar KKn\pi $$ (n=1÷5) at momentum 3.0, 3.6 and 4.0 GeV/c have been analysed, and partial cross-section for the various channels are given. The total cross-sections for annihilation into two kaons with pions is estimated to be (5.1±0.4) mb or 14% of all annihilations. The amounts of resonant K*(890), ρ, ω and associated K*K* production in the various channels are determined. Evidence for the E-meson, a KKπ resonance at 1700 MeV, and a K*π resonance at 1265 MeV is presented. Study of 955 unfitted events containing two charged particles, a K 1 0 and ≥2 neutral secondaries gives rise to a four-standard-deviation peak in a strangeness-zero mass spectrum at (1820±12) MeV with a width (Γ) of (50±23) MeV. The angular distributions favour a peripheral rather than a statistical or core-core model of the annihilation process. The possible usefulness of weighting the various combinations in accord with this observation, to accentuate enhancements in the invariant-mass distribution, is discussed. A method of separating each annihilation into its most likely two-body final-state configuration based on maximizing the four-momentum transfer (u) in the cross-channel is presented as well as some examples of the enhancements in mass spectra obtained using this method.
