摘要：

Important new data of McNaughton et al. on np Wolfenstein parameters are added to NN phase-shift analysis. At 800 MeV, there is a dramatic improvement and one can see with confidence which way phase shifts are heading from 500 to 800 MeV. Dispersive effects in 3D1 and 3G3 herald the onset of I = 0 inelasticity. Phase shifts account naturally for the energy dependence of DELTA-sigma(L) and DELTA-sigma(T) for np scattering and do not support the claim of Beddo et al. for an I = 0 dibaryon resonance near 733 MeV.
