We have measured the differential cross sections for K − p→ Σ + π − and K − p→ Σ − π + scattering, and the polarization distribution of the Σ + in the first reaction, at K − lab momenta of 3.13 and 3.30 GeV/ c . Our K − p→ Σ + π − cross sections are at least 40% larger than interpolations between measurements at nearby momenta. A comparison using isospin conservation of K − p →Σ + π − , K − p →Σ − π + , and K 0 p → Σ 0 π + cross sections favors our results. The K − p→ Σ + π − differential cross sections have about the same shape and are about twice as large as corresponding K − p→ Λπ 0 differential cross sections across the whole forward region. We discuss the results briefly with reference to simple exchange models.

We present data on K − p reactions leading to the final states K 0 n , π 0 Λ, ηΛ, η'Λ, π − Σ + , K 0 Δ 0 (1230), and π − Σ + (1385) from a bubble chamber experiment at 14.3 GeV/ c K − lab momentum. Total and differential cross sections, Λ and Σ ∓ polarisations in π 0 Λ and π − Σ + final states as well as the Σ + (1385) density matrix elements are given.
