The reaction K−n→Σ−η has been studied near threshold. The production angular distribution and the cross-section as a function of energy were measured. The combined angular distributions of this experiment and two previous ones suggest that aJ=1/2 amplitude dominates in Σ−η production. Our cross-section can be fitted with a Σ−1η resonance of mass 1785±12 and width 89±33, or it can be fitted in a zero-effective-range scattering approximation with a scattering length of (0.92±0.12)±i(0.04±0.28) fm.

Final states π − Σ + , π + Σ − , π o Λ and ηΛ were studied for K − p reactions at 3.95 GeV/ c . Cross sections, angular distributions and polarizations are presented. Data for π − Σ + and π o Λ production are compared to the line-reversed πp reactions at the same beam momentum. Baryon-exchange peaks are presented for the Σ + π − , Σ − π + and Λπ o final states.
