Total Cross Sections for π-p-->ΛK0 from Threshold to 1.13 GeVc

Total cross sections for π^-p-->ΛK⁰ have been measured using optical spark chambers from threshold to 1.13-GeVc beam momentum in 19-MeVc intervals, but with a 1-MeVc resolution in the regions of the ΛK and ΣK thresholds. The behavior near ΛK threshold indicates a significant s-wave contribution, but this experiment is unable to resolve any cusplike behavior in the region of the ΣK thresholds. The cross section shows a broad peak in the vicinity of 1.05-GeVc beam momentum.
