Reaction K−p→π0π0Σ0 was measured with the Crystal Ball multiphoton spectrometer at eight K− momenta from 514 to 750MeV∕c. Dynamics and the energy dependence of the reaction are shown by Dalitz plots, invariant mass spectra, production angular distributions, and total cross sections. The dipion invariant-mass spectra for K−p→π0π0Σ0 show an enhancement in the low mass region; the opposite is the case for the K−p→π0π0Λ and π−p→π0π0n reactions. There is no direct evidence for a f0(600)-meson contribution to π0π0 production. Everywhere σt(K−p→π0π0Σ0)⪡σt(K−p→π0π0Λ).
