摘要：

We present measurements of the differential and total cross sections and the Lambda polarization for the reaction K(-)p --> eta Lambda from threshold to PK- = 770 MeV/c, with much better precision than previous measurements. Our cross-section data show a remarkable similarity to the SU(3) flavor-related pi (-) p -->etan cross-section results. The reaction K(-)p --> eta Lambda at threshold is dominated by formation of the intermediate Lambda (1670) 1/2(-) state.
