Deuteron breakup processes p+d→ (NN)s,t+N are studied in the kinematics of backward elastic pd-scattering at law relative momenta of the NN-pair k∼ 0-50 MeV/c for initial energies T0=0.5-2.5 GeV in the framework of the known mechanisms of the pd→ dp process including rescatterings in the initial and final states. A considerable suppression of the Δ- and N^*- isobar excitation mechanisms is found for the production of the singlet (NN)s-pair. As a result, one nucleon exchange mechanism can be identified in the cross section and polarization observables by the node of the half-off-shell NN(~1S0)-scattering amplitude, t(q,k), at q∼ 0.4 GeV/c.
