The [ital NN][r arrow][ital N][Delta] reaction is investigated within the coupled [pi][ital NN]-[ital NN] theory. The model predictions for the differential cross section, production asymmetry, and spin-correlation parameters are compared with the Argonne data at [ital T][sub [ital N]][sup lab]=0.57, 0.81, and 1.01 GeV. Short-range effects are introduced through the [rho]-exchange contribution. The overall quality of the results is satisfactory, except for the triplet part of the production asymmetry at the two highest energies. The role of the [sup 3][ital F][sub 3][r arrow][sup 5][ital P][sub 3] amplitude in this problem is assessed.
