We have studied the reactions K-d→pΣ0π0 in the the Σπ mass range from 1600 to 1800 MeV. The cross section and angular distributions obtained are represented in a partial wave parametrization. We find a resonant amplitude of the D13 wave around a mass of 1680 MeV. The amplitude is if TR= √Λ(Σπ)·Λ(KN) = 0.19, independent of the behaviour of background amplitudes. © 1969.
