NN → πD amplitudes from 400 to 800 MeV

New data from SIN and LAMPF improve substantially the determination of NN → πd amplitudes. Data of the Geneva group on spin transfer from proton to deuteron it11 and t22 polarisations determine magnitudes and phases of two amplitudes previously poorly known, namely a5 (3F2) and a7 (1D2→lπ = 3), up to 580 MeV. Three new sets of LAMPF data determine a7 and the magnitude of a5 up to 800 MeV and a8 (1G4), a9 (3F3 → lπ = 4) and a10 (3F4) at 800 MeV. The a7 amplitude is qualitatively more plausible than earlier values; a5, a8, a9 and a10 agree with expectation. The determination of amplitudes is now essentially complete except for the phase of a5 above 580 MeV.
