Measurement of $\pi^0 \Lambda$, $\bar{K}^0 n$, and $\pi^0 \Sigma^0$ production in $K^- p$ interactions for $p_{K^-}$ between 514 and 750 MeV/$c$

Differential cross sections and hyperon polarizations have been measured for K(0)n, pi(0)Lambda, and pi(0)Sigma(0) production in K(-)p interactions at eight K- momenta between 514 and 750 MeV/c. The experiment detected the multiphoton final states with the Crystal Ball spectrometer using a K- beam from the BNL Alternating Gradient Synchrotron. The results provide significantly greater precision than the existing data, allowing a detailed reexamination of the excited hyperon states in our energy range.
