Application ofπ−NScattering Results toΛ−K0Production

The appearance of numerous phase-shift analyses of pion-nucleon scattering and the tentative identification of resonances in that process lead naturally to an application of these results to processes involving other decay channels. We choose the three isospin-½ resonances of the $\pi -N$ system on which there seems to be the widest agreement and consider their effect on the process ${\pi }^{-}+p\to \Lambda +K^0$ near 900 MeV. The background term which we use is a $K^{*}$ pole modified by an arbitrary constant factor of modulus unity. A comparison with available data is given for various resonance pairs and for the three resonances together.
