Abstract: (Elsevier)

A meson exchange model, which includes final-state interactions, leads to a fair account for the scarcely available experimental cross sections of the pp → ppη and np → d η reactions. The ϱ-exchange transition amplitude NN → NS 11 (1535) is found to dominate. Predictions for exclusive reaction cross sections are given.
