Abstract: The possibility for an observation of a narrow penta-quark Z+-baryon in NN reactions is discussed. It is shown that the pp→nΣ+K+ reaction at excess energies around 100 MeV above threshold provides optimal conditions for Z+-baryon detection by an analysis of the nK+ invariant mass spectrum, if the Z+ mass is located around 1.5 GeV involving a rather narrow width.
