New data on the reaction K-n→(Σπ)- and a partial wave analysis of anti KN→Σπ in the energy range 1520-1745 MeV

Differential cross sections for K-n→Σ-0π0- have been measured at K- momenta between 680 and 840 MeV/c in a bubble chamber experiment. For K-n→Σ0π- the Σ0 polarization was also determined. The measurements were combined with the available data on K-p→Σπ in an energy-dependent partial wave analysis in the center of mass energy range from 1520 to 1745 MeV. An acceptable fit was obtained with the well established resonances. (Auth.)
