Fasano, M. Locher] Spectator nucleon distributions in¯pd →mπN are directly related to the antiproton-nucleon annihilation process below threshold. To demonstrate this quantitatively, we analyse the available¯pd → 3πN and¯pd → 5πN data. For these data, (and others) the shape of the annihilation spectrum in the peak region is well described by the tree diagram, and reflects mainly theS-state part of the deuteron wave function. The data are not consistent with a strong structure in the antinucleon-nucleon sub-thresh-old amplitude as reported in the dispersion analysis of¯pp while a weak structure is consistent with the existing data.
