A precision measurement of the angular distribution of the analyzing power of the reaction p + p → d + π+ has been made at 0.8 GeV. It is shown that none of the existing theoretical calculations, including those which introduce resonant dibaryon amplitudes, reproduce even the qualitative features of the data. It is concluded that our data do not require dibaryon admixtures of the kind proposed for the interpretation of recent data on vector analyzing power, iT11(θ), of π-d elastic scattering at the same center of mass energy.
