Associated production of strange particles at resonance energies

Data are quoted from two recent experiments on the measurement and analysis of the reaction π-p→Λ0K0, one performed with counter techniques at NIMROD the other at Saclay with the 2 m HBC. The distribution of the data in energy for the two experiments are shown, together with the πN resonances as proposed by the CERN and Saclay elastic phase shift analysis respectively. Partial wave analysis of the data is discussed, and the masses, widths and couplings obtained in the two analyses are tabulated. The resonance parameters are considered. (U.K.)
