Abstract: 
We investigate the cross section for the reaction NN --> N Na-0 near the threshold and at medium energies. An effective Lagrangian approach with a one-pion exchange is applied to analyse different contributions to the cross section for different isospin channels. The Reggeon exchange mechanism is also considered. The results are used to calculate the contribution of the a(0) meson to the cross sections and invariant K (K) over bar mass distributions of the reactions pp --> pn K+ (K) over bar (0) and pp --> ppK (+) K- . We found that the experimental observation of a' mesons in the reaction pp --> ppK(+)(K) over bar (0) is much more 0 promising than the observation of a(0)(0) mesons in the reaction pp --> ppK(+) K- .
