Abstract
We report the first measurements of the total cross section of the reaction K-p→Σ0γ at eight beam momenta from 514 to 750 MeV/c. The data were obtained at the Alternating Gradient Synchrotron (AGS) at Brookhaven National Laboratory using the Crystal Ball detector consisting of 672 NaI crystals. All charged particles were vetoed by a barrel of plastic scintillators, resulting in a study of only the neutral decays of the Σ0. The prompt photon and the photons from the decay products of Σ0 were detected for each reconstructed event; the neutron was also detected in a small fraction of the events.
