The angular distribution and polarization for the reaction K − n→ π − Λ have been measured in the c.m.s. energy range 1750 MeV to 2000 MeV by means of a bubble chamber experiment, producing on average 500 events of this type per 10 MeV energy interval. The data are compared with the predictions of a recent partial-wave analysis of this reaction.

Experimental details and channel cross sections are presented for five K − deuterium bubble chamber experiments. Utilising the Fermi motion of the neutron the K − n cross sections are extracted over the c.m. energy range 1750–2200 MeV and where possible results are compared to related channels from other experiments.

Results are reported on K − -neutron interactions at c.m. energies near 2 GeV. The interactions are dominated by strong production of hyperon resonances, particularly Σ(1385), Λ(1405) and Λ(1520). Production cross sections and angular distributions are given for the Σ(1385), Λ(1405) and Λ(1520) and branching fractions to decay modes observed in the experiment are given for Σ(1385) and Λ(1520). The strong energy dependence of some features of the data suggests that s -channel effects are dominant.
