We measured cross sections and vector analyzing powers of the breakup reaction {sup 2}H({ital p}{searrow},{ital pp}){ital n} at a laboratory proton energy of 19.0 MeV in four kinematically complete arrangements comprising space star, collinearity, final-state interaction, and quasifree scattering conditions. We present our results and compare them to the predictions of rigorous three-nucleon Faddeev calculations using different realistic nucleon-nucleon potentials. We found cases of good agreement but also cases of clear discrepancies. The inclusion of the 2{pi}-exchange Tucson-Melbourne three-nucleon force does not remove these discrepancies but even worsens the description in all cases. In the quasifree scattering and space star configurations Coulomb-force effects might possibly be responsible for at least part of the observed discrepancies. {copyright} {ital 1996 The American Physical Society.}
