The large variety of experimental data around the pion-production thresholdare compared with a meson-exchange isobar model which includes the pion-nucleoninteraction in s-- and p-waves. Theoretical results obtained with two differentNN potentials (Bonn and Paris) indicate that the behavior of the excitationfunction at threshold is sensitive to the details of the NN correlations. Thecomplete model presented, while developed originally to reproduce the reactionaround the Delta resonance, is shown to describe well the integral(Coulomb-corrected) cross-section at threshold along with its angulardistribution. At low energies the angular dependence of the analyzing power Ay0is well reproduced also. Finally, the energy dependence of the analyzing powerfor theta=90 from threshold up to the Delta resonance is considered anddiscussed.Comment: 14 pages, REVTeX, plus 6 figs., Postscrip
