A model calculation for near-threshold h meson production in
nucleon-nucleon collisions is presented. The h meson production
is described by elementary rescattering processes via MN ® hN, with M = p, r,
h and s. Corresponding amplitudes
are taken from a multi-channel meson-exchange model of the pN
system developed by the Jülich group. Effects of the NN interaction in the final as well
as in the initial state are taken into account microscopically.
