The decay p̄p (at rest) → KoL K ± π ∓ πo, studied on a sample of more than 14000 events, is found to proceed dominantly via two-body channels containing resonances with open strangeness. Contributions from K1(1270) K̄ and K1(1400)K̄, branching into the successive K1-decay modes, and from K * K̄ *, K * (K̄π)S and (Kπ)S(K̄π)S are extracted by means of a partial-wave analysis which accounts well for the data and also allows a search for weak contributions from other (Kππ) and from (KK̄π) resonances. Striking asymmetries between the charged and the neutral kaonic resonances give evidence for interfering isospin 0 and 1 annihilation amplitudes.
