The reaction K{sup -}p{yields}{sigma}{sup 0}{pi}{sup 0}{yields} neutrals was studied with the Crystal Ball detector at the BNL Alternating Gradient Synchrotron for beam momenta between 514 and 750 MeV/c. The photons from {sigma}{sup 0} and {pi}{sup 0} decays were detected, as well as the neutron in a small fraction of the events. The differential cross section and the {sigma}{sup 0} polarization are reported at eight momenta and nearly the full angular range. Total cross sections are derived from Legendre polynomial fits to the data. The measurements presented are of considerably higher precision than previous results.
