Differential and channel cross sections for the reactions KL0p → KS0p and KL0p → Λ0π+ in the c.m. energy range 1605 to 1910 MeV

The differential and channel cross sections have been measured for the reactions K_L⁰p → K_S⁰p and K_L⁰p → Λ⁰π⁺ 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 $\text{K}\text{N}$ amplitude (I = 1) and is very sensitive to the various KN phase-shift solutions, some of which show an exotic I = 0, P₁ resonance. Our results have been expressed in terms of frequency distributions and cross sections, normalised by the Λ⁰π⁺ reaction. These results have been compared with the predictions of various partial-wave analyses. Qualitatively we can eliminate the P₁ non-resonant solution, though no solution correctly predicts our results.
