Abstract
We have used an optical spark-chamber spectrometer to perform a systematic study of the reaction ${\ensuremath{\pi}}^{\ensuremath{-}}p\ensuremath{\rightarrow}\ensuremath{\Lambda}{K}^{0}$ at beam momenta between 930 and 1130 MeV/c. The cross section, angular distribution, and $\ensuremath{\Lambda}$ polarization have been measured. We present our complete data from a sample of 11 400 events along with Legendre polynomial coefficients for the angular distributions. No striking cross-section enhancement at $\ensuremath{\Sigma}K$ threshold is observed, but there is evidence for a small cusp effect. A simple model which takes account of the $\ensuremath{\Sigma}K$ channel provides a good fit to our data.
