The differential and channel cross sections have been measured for the reactions K L 0 p → K S 0 p and K L 0 p → Λ 0 π + in nine energy intervals in the c.m. range 1605 to 1910 MeV. The regeneration reaction is a combination of the KN amplitudes (with I = 0 and 1) and the K N amplitude ( I = 1) and is very sensitive to the various KN phase-shift solutions, some of which show an exotic I = 0, P 1 resonance. Our results have been expressed in terms of frequency distributions and cross sections, normalised by the Λ 0 π + reaction. These results have been compared with the predictions of various partial-wave analyses. Qualitatively we can eliminate the P 1 non-resonant solution, though no solution correctly predicts our results.

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.

A partial-wave analysis of the pure isospin I = 1 reactions K−n→Σ−π0 and K−n→Σ0π− in the center-of-mass energy range 1850-2150 MeV is reported. The decay mode Σ(2030)→Σπ is observed with a branching ratio xr given by eiφ(xexr)12 = −0.085±0.02, where xe is the elasticity and φ is the relative phase of the resonance with the phase of Σ(1765) taken to be zero.
